FIRST ANNOUNCEMENT

CLASS, the International Conference on Liquid Atomisation and Spray Systems, is the foremost international gathering of sci-

entists, engineers and students to discuss re-search, development, technology and applica-tions related to atomisation and sprays.

ICLASS - 2003 is the 9th such triennial confer-ence, held on a rotating basis in Asia, America, and Europe. Previous conferences have been held in Tokyo (1978), Madison (1982),

London (1985), Sendai (1988), Gaithersburg (1991), Rouen (1994), Seoul (1997) and Pasa-dena (2000).

Venue The conference will be held at the Congress Centre of the "Sorrento Palace Hotel", Sor-rento, Italy.

Surrounded by lush greenery and overlooking Mount Vesuvius, the Sorrento Palace's facilities include a modern conference centre. The hotel

has 400 rooms, all with air conditioning, as well as two swimming pools, six restaurants and three bars.

Sorrento is very well endorsed in the context of the gulf of Naples. The name of Sorrento means "city of Sirens" the mythical enchantress who tried in vain to seduce Ulysses and ended up being turned into the three magnificent is-lands forming the nearby archipelago known as "Li Galli".

Founded by the Greeks, Sorrento is like a mo-saic full of monuments, from the Cathedral and its paintings by the Naples school, to the de-

lightful Arabic-style cloister in the San Fran-cesco Convent.

There are numerous archaeological sites around the town, such as the temple of Athens at Punta Campanella or the Baths of Queen Joan at Capo di Sorrento. Nature is also closely linked to history. Rising up from the very edge of a tuff stone cliff, Sorrento is clearly identifiable by the colour of its time-honoured

olive and walnut trees, the intoxicating perfume of its citrus orchards, all the work of the mildest of Mediterranean climates.

Sorrento can be considered the very heart of what Romans called "Campania Felix". It takes only a short boat ride to experience the fascina-tion of Ischia, famed for its lush green vegeta-tion and therapeutic spa waters. The island of Capri, both elegant and wild, is only 15 minutes by hydrofoil. A few kilometres drive will step you back two thousand years to the world-famous archaeological sites of Pompei, with its vil las and frescoes, and slightly further away, the equally beautiful Herculaneum.

Only a half hour by hydrofoil brings you to the ancient heart of Naples, an extraordinary city buzzing with history, art and culture. Sorrento is also an excellent starting point for a visit to the Amalfi Coast to savor the picturesque vil-lage of Positano, the former maritime Republic of Amalfi and the breathtaking panorama from the heights of Ravello.

n agriculture spraying systems are used mainly to apply plant protection products. Chemical crop protection is absolutely essential to protect

plants against harmful organisms and weeds in or-der to prevent a decline in yields and to help to en-sure security of supplies. However, chemical plant protection may involve risks and hazards for hu-mans, animals, for the environment in general. Those risks are mainly caused by spray drift or evaporation of active substances as well as by soil contamination and run-off. This could lead to pollu-tion of surface and ground water and to contamina-tion of non-target organisms. Therefore these products have to be officially tested and author-ised. During this procedure restriction for the use of the chemicals are defined. Plant protection products may be formulated as water soluble powder, suspension or emulsion and are generally diluted in water before application. Their biological efficacy has been increased dra-matically during the last decades, so in many cases only a few grams of active ingredients are to be applied per hectare. However, the amount of water as carrier stuff remained at a range of 100 to 1000 litres per hectare for arable crops and of up to 2000 litres per hectare in orchards. This is nec-essary to ensure an even distribution of the chemi-cal on the target area and to achieve an appropri-ate deposition at defined layers of the canopy. Sprayers range from knapsack equipment to field sprayers with booms of up to 48 m width. The ma-jority of these sprayers is equipped with nozzles which atomise the spray liquid by pressure. Maxi-mum spray pressure is about 2000 kPa, the nozzle output ranges from 0.5 to 5 l/min. In some cases twin fluid nozzles or rotary atomisers are used. Application technique can provide a significant contribution to both biological efficacy and envi-ronmental protection. One of the most important criteria for the evaluation of agricultural atomisers

is the droplet size spectrum. A fine spray gives a very even deposit distribution on the surface of the leaves. It does not penetrate the canopy and is therefore appropriate to treat ears and upper leaves of cereal crops. Fine sprays are prone to drift and evaporation. Coarse sprays are more appropriate to penetrate the crop canopy

to treat the lower parts of the plants. With those sprays the risk of soil contamination and run-off is higher. So efficacy and

environmental protection may condition contrary requirements on droplet size spec-tra of a spray. Since the impor-tance of environ-mental aspects has been increas-ing, a tendency towards coarser sprays is ob-tained. This is also supported by a growing "toler-ance" of new type

pesticides regarding deposit structure. Nozzle manufacturers came up with some interest-ing types of nozzles providing coarser sprays at the same output rate. One of those types is the so-called pre-orifice nozzle. It has an aperture before the nozzle orifice to adjust the flow rate. The real nozzle orifice is assigned only with the atomisation. Since a pressure loss occurs at the pre-orifice, at-

omisation gives bigger droplets. Even coarser sprays can be generated using air induction noz-zles. Those have an inductor to define the flow rate and to suck air into the liquid flow. For certain for-mulations of the spray liquid air bubbles may be included in the droplets. Hitting the target, those droplets burst and a fine deposit structure is pro-duced. So ideally aims, high efficacy and low drift as well, are achieved. It follows that droplet size spectrum is one of the most important criteria when atomisers are evalu-ated. So many of the institutions dealing with sprayer testing own a droplet sizing system. De-vices based on laser diffraction (LD) and Phase Doppler effect (PDA) are spread for droplet sizing on agricultural spray atomisers. A new develop-ment is the so-called Particle/Droplet Image Analy-sis (PDIA). Tests have shown that the International BCPC Spray Classification System is very useful to en-sure that measuring results from different laborato-ries can be compared. The classification of sprays from almost all tested nozzles gave the same re-sults for all measuring systems.

Spray classification results were nearly independ-ent from whether the classification was based on the whole spectra or on the volume mean diameter VMD. Normally the whole spectrum should be con-

sidered and the spray should be classified accord-ing the position of the major part of the cumulative volume distribution. But it can be seen that the spectra in each classification scheme have charac-teristic shapes. If a spectrum crosses a border line, it is very likely that the VMD represents the major part of the spectrum. For that reason, classification by VMD should be appropriate for spray classifica-tion at least for conventional pressure atomisers.

Significant differences in measuring results from sev-eral droplet sizing systems were found. Differences in-crease with droplet size. This region of droplet size spectra recently gets more important for environmental protection reasons. That is why a reference system is essential especially for the comparison of droplet sizing results from coarse nozzles. In the USA the International BCPC Spray Classification System was extended by an “extra coarse” class using an additional reference nozzle. This should

be introduced generally in order to increase the sensitivity of the system for coarse nozzles. Then the International Organization for Standardization should by applied to for giving this de facto stan-dard an official status.

ILASS-EUROPE Institute for Liquid Atomization and Spray

Minutes of 17th Annual General Assembly (AGA)

of ILASS Europe held on September 3rd in

Zürich, Switzerland

Item 1 Opening and Approval of Agenda. Our Chairman, Mr. Bendig opened the meeting and thanked all attendees for being present. The agenda was approved as tabled. A discussion on membership status was proposed by Mr. Bendig for item 11 of the agenda. Item 2 Approval of the minutes of the last AGA in Darmstadt 2000. The minutes have been posted during the day and distributed previously as part of the newsletter to all members. Furthermore, copies were distributed during the meeting. The minutes were accepted unanimously. Item 3 Messages from the Chairman, Vice-Chairman and Secretary. Mr. Bendig reported more than 180 registrants for the Annual Scientific Meeting (ASM) with 138 pa-pers and posters presented. This makes the Zürich ASM the fifth consecutive successful symposium which proves the ASM a well established scientific forum for the exchange of information and presen-tation of the most recent results on all aspects of atomization and sprays. The Vice-chairman, Prof. Cavaliere, expressed his satisfaction with the numbers presented and espe-cially pointed out the importance of a growing European science within the European Union. The Secretary, Dr. Haidn, pointed out that all at-tendees who are interested in ILASS Europe would find copies of the constitution of ILASS Europe and

the latest Newsletter on the desk at the entrance to the meeting room as well as membership applica-tion forms at the registration desk and at the en-trance of the main theatre. He briefly mentioned that last year ILASS Europe had around 110 members which dropped to around 70 as of today. Item 4 Message from ILASS International. Prof. Chigier, the actual Chairman of ILASS Inter-national briefly addressed the audience and men-tioned the growing interest in ILASS International might rise a need for a more professional organiza-tion. Item 5 Treasurer’s Report. The treasurer, Dr. Ragucci, reported the problems with the four accounts ILASS Europe has in the United Kingdom, Germany, France and Italy to avoid losses in connection with money transfers across borders. The board hopes to improve the legal situa-tion of ILASS Europe within the upcoming years. The treasurer reported that he as co-organiser of ICLASS 2003 will, with the approval of the board, start spending ILASS Europe money for the or-ganisation of the next ICLASS in Sorrento. Item 6 Report of Newsletter Editor. Dr. Marengo gave a brief report on the number of Newsletters issued since the last AGA and said that he his planning to issue as usual two Newsletters per year. He again asked the audience for an active input in form of information about research fields of groups, scheduled workshops and conferences, and any other matters which could be of interest to the community. He also pointed out that he wanted to continue the se-ries of contributions from different research groups. Item 7 Report from the Web-Page Editor Dr. Shrimpton was excused absent and Mr. Bendig reported that all papers of the 2000 ASM are now available in pdf format and he thanked Dr. Shrimp-ton for all this effort and for establishing the current ILASS Europe web pages.

Item 8 Organization of ICLASS 2003 The Chairman reported from the first organisational meeting in April in Sorrento where the main topics have been discussed. As a result, three commit-tees, the steering committee headed by Mr. Bendig, the scientific committee headed by Prof. Balachandran and the local organisational commit-tee headed by Dr. Ragucci were established with Prof. Cavaliere as coordinator.

? ? Dr. Ragucci presents a first announcement and reported that Dr. Marengo has already put it in the internet.

? ? Prof. Balachandran mentioned that the scien-tific committee will be established within the next couple of weeks and the first announce-ment and call for papers will be ready for distri-bution prior to the end of the year.

Item 9 Election of officers and committee members Mr. Bendig reported that the terms of the following officers and committee members end today :

Antonio Cavaliere (Vice - Chairman) Iskender Gökalp Eva Gutheil Günther Schulte Eran Sher Graham Wigley

Being asked by the Chairman, all those people ex-pressed their willingness to serve for another pe-riod. Then Mr. Bendig asked the audience for fur-ther candidatures but none were forwarded. The candidatures of Cavaliere, Gökalp, Gutheil, Schulte, Sher and Wigley were accepted unani-mously.

Item 10 Location of next Annual Scientific Meetings As already decided earlier, the 18th ILASS Europe Conference will be held in Saragoza in early Sep-tember 2002. The organizer, Dr. Lozano, briefly addressed the audience and mentioned the first announcement which has been distributed by mail, is in the web and posted at the ASM. Since ILASS Europe is organising the upcoming ICLASS conference in 2003, the next ILASS

Europe conference will take place in 2004. So far, two proposals have been made by Prof. Eran Sher from Ben Gurion University in Beer Sheva and Dr. Gökalp from the CNRS Orleans. After a brief dis-cussion the audience agreed upon that first, there is no need for an urgent decision since we the ASM in question is the one of 2004, and, second, that more proposals should be made. Guidelines for potential organisers are available from either Lothar Bendig Andrew Yule. Item 11 Miscellaneous The issue of ILASS Europe membership was dis-cussed at length. The secretary explained that people become a member when the fees are paid either with Andrew Yule in the UK, Günther Schulte in Germany, Lelo Ragucci in Italy or Chris-tophe Dumouchel in France. With people changing affiliation quite often it is impossible to have an up-to-date status of the membership at any time. Beat Ineichen mentioned that based on his experience as ASM organizer, he estimates the time neces-sary to keep the address list updated to about 2-4 days per month. Various proposals were made to simplify the pro-cedure: Norman Chigier mentioned the American way of establishing a life-time membership once you have attended an ILASS Americas confer-ence. Oskar Haidn explains the idea which was proposed by John Shrimpton earlier to skip the fees because the amount of money is to small anyway and irregular establish a useful continuous spending and to create a web-page where every-body can become a member by identifying himself and renew his interest on a yearly basis. Cam Tropea identifies three main issues; first, How does ILASS Europe establish membership?, sec-ond, the problem of keeping an updated member-ship list which is a much smaller problem than the necessity of an updated list of possible attendees for the ASM, a must for each ASM organizer, and, third, What is ILASS Europe about? He further proposed to leave the final decision to the board. The floor agreed to proposal from Mr. Bendig that the officers will prepare alternatives and present them for final decision at the next AGA. Lampoldshausen, October 2001 Dr.-Ing. Oskar J. Haidn
