Course Description

1. Overview of the course:

The course content is designed to explain both conventional and non conventional energy sources

In conventional power plants such as thermal, diesel and hydel power plants ,students are supposed to

explain in brief about the general layout of thermal power plants with circuits such as coal handling,

boiler feed and steam supply, ash disposal, steam turbine, electric generation and its transmission.

In non conventional energy sources, importance of solar energy and its applications in various areas

through collectors are explained, methods of generating electric energy through geothermal power,

OTEC, biomass conversion, concept of green energy are illustrated.

2. Relevance of the course:

The energy requirement in modern world is increasing every day. The present conventional

energy is unable to meet the demand. Non conventional energy is the field to be exploited. The

knowledge of energy engineering is required for present day engineers.

Renewable resources covered here include: electricity produced from the light of the sun via

photovoltaic cells on individual buildings or for communities of buildings, or for the production of

central station power in vast arrays; from the heat of the sun, again for localized tasks like providing

homes and businesses with hot water or space heating, or providing central station power using fields of

parabolic collectors focused on a fixed hot water source or solar ponds, from the power of the wind,

from the heat below the earth through various geothermal applications, from the power of ocean tides

and waves, from the temperature variations between ocean surfaces and depths, from small

hydroelectric installations, from agricultural wastes through biomethanation, and from biomass crops

grown for energy use or from crop waste cellulose, the biomass can be refined to produce ethanol or

gasified for heat, electric and transportation applications.

Traditional biomass in the form of firewood is not covered as a renewable resource, however,

because it most often involves the cutting down of ecologically valuable forests that act as protection

against floods and erosion and as sinks for carbon dioxide and because the gathering of firewood is so

debilitating to women and children who also suffer serious health hazards when the firewood is burned

in enclosed spaces for heating and cooking. The same is true of burning animal dung for heating and

cooking. However, so-called modern biomass consisting of crops to ethanol and gasified wood and crop

wastes is included.

3. Applications areas:

The applications of the Renewable energy resources are found in all fields of energy technology, in

steam and nuclear power plants, internal combustion engines, air conditioning, refrigeration, gas

dynamics, jet propulsion, compressors, chemical process plants, and direct and indirect energy

conversion devices.

4. Pre-requisites

The students should have knowledge about the conventional energy sources,

&thermodynamics.

5. Course Outcomes (COs):

After a successful completion of the course, the student will be able to:

1. Identify different types of fuels used for steam generation

2. Apply energy conversion principles to diesel, hydro energy sources.

3. Understand the basic concepts of solar radiation and analyze the working of solar PV and

thermal systems.

4. Explain principles of energy conversion from alternate sources including wind,

geothermal, ocean, biomass, biogas.

5. Explain the concepts and applications of fuel cells, thermoelectric convertor and

MHD generator.

Overview of the Course:

In recent years, the concept of automatic control has achieved a very important position in the

modern technology. Optimization and automation principles are improving the static and transient

behaviors of the control systems. The stability analysis and the design of such control systems is the

challenge before today’s engineer. The control systems find applications in the wide variety of

engineering branches. From this point of view, VTU has introduced a course on “Control Engineering” at

VII Semester of Mechanical Engineering branch.

The course deals with

Relevance of the Course:

Automatic control systems have played an important role in the advancement and

improvement of engineering skills. Practically, every activity in our day to day life is influenced

by some sort of control system. Concept of control systems also plays an important role in the

working of space vehicles, satellites, guided missiles etc. such control systems are now integral

part of the modern industrialization, industrial processes and home appliances. Control systems

are found in number of practical applications in all the engineering disciplines. Hence for an

engineer it is absolutely necessary to get familiar with the analysis and designing methods of

such control systems.

COURSE DESCRIPTION:

Prerequisites:

This subject requires the student to know the basics of Engineering, Mechanics of Deformable

Bodies, Material Science, Fluid Mechanics Analysis of Tribological aspects of machine components,

including friction, lubrication, and wear, basics of Physics & other related engineering fields.

Overview of the Course:

Tribology is the science and application of the principles of friction, wear and lubrication Tribology is an

interdisciplinary science based on know-how and expertise from different fields such as mechanical

engineering, materials science and engineering, chemistry and chemical engineering. Tribology involves:

Friction – the resistance to motion of one body moving against another

Wear – the loss of material due to motion

Lubrication – the use of a fluid to minimize friction and wear

In recent years, tribology has become increasingly important in the field of sheet metal forming as it

takes into account the effects of motion as well as the interaction between sheet material, lubricant and

tool or coating material during the forming process. These tribological interactions influence the final

quality of the formed parts as well as the stability and efficiency of the production process.

The course deals with

7. Understand the fundamentals of tribology and associated parameters

8. Applying concepts of tribology for the performance analysis and design of components

experiencing relative motion.Understand what are block diagrams and signal Flow

9. Analyzing the requirements and design hydrodynamic journal and plane slider bearings for a

given application.

10. Selecting proper bearing materials and lubricants for a given tribological application.

11. Applying the principles of surface engineering for different applications of tribology.

Relevance of the Course:

The study of friction, wear, and lubrication is of enormous practical importance, because

the function of many mechanical, electromechanical, and biological systems depends on the

appropriate friction and wear values. In recent decades, this field, termed tribology, has received

increasing attention as it has become evident that the wastage of resources resulting from high

friction and wear is greater than 6% of the Gross National Product. The potential savings offered

by improved Tribological knowledge are immense. Special consideration should be given to the

application of fundamental knowledge to control friction and wear behavior through lubrication

and the selection of materials and coatings in practical situations.

Applications Area:

Most common components (rolling or sliding):

• Bearings

• Gears

• Cams

• Brakes

• Seals

We see that most common elements/components, which are used in number of machines, machines

which have relative motion, any rotary motion, any sliding motion, take an example of car, which is an

automobile, aircraft, turbines, any compressor all these require tribo elements, they require some sort

of sliding motion, some sort of rotational motion. And that is why we require, application of tribology to

design those components, which are utilized for relative motion under load.

Course Outcomes (COs):

After studying this course, students will be able to:

CO1: Understand the fundamentals of tribology and associated parameters.

CO2: Apply concepts of tribology for the performance analysis and design of components experiencing

relative motion.

CO3: Analyze the requirements and design hydrodynamic journal and plane slider bearings for a given

application.
