Course objectives

By the end of this course you should be able to:

1. Identify the difference between different types of flows: Newtonian and Non-Newtonian, compressible and incompressible, and steady and unsteady.

2. Calculate the viscous shear stress due to liquid motion.

3. Calculate hydrostatic forces on plane surfaces.

4. Use Bernoulli equation to relate fluid velocity, pressure, and elevation.

5. Represent a velocity field in terms of the velocity components (u, v, and w).

6. Draw the flow streamlines from knowledge of equations of velocity components (u and v) in two dimensional flows.

7. Calculate forces and torques on surfaces and bodies due to moving fluids.

8. Use similitude and common dimensionless groups to predict performance of real systems from that of laboratory models.

9. Calculate pressure drop in pipes as a function of flow rate and pipe dimensions.

10. Use manometers and diaphragm sensors to measure pressures.

11. Use venture meters and Pitot tubes to measure fluid velocity.

Term projects

Students will be formed in groups of 3-6 students each and will be assigned a term project to

research on their own. Project topic should involve fluid flow on one way or another. At the end

of the semester, each group will be required to give a 5 minutes presentation about their project

and submit a report (minimum 3 pages, maximum 5 pages, not including the cover).

Sample topics for term project

The following is a list of sample topics that can be chosen. Students can suggest other topics

upon instructors approval. 1. Liquid lens 2. Electrowetting displays 3. Digital microfluidics 4. Electroosmotic flow 5. Dean flows 6. Droplet motion using thermocapillary 7. Marangoni flow: Why do coffee stains form? 8. Calorimetric flow sensors 9. Capillary pumping in microchannels 10. Capillary electrophoresis 11. Applications of laminar flow in microchannels 12. Bullet proof liquid armors 13. Optoelectrowetting 14. Microchannel heat sinks

Important dates

First midterm: Week of March 15th, 2015 Second midterm: Week of April 18th, 2015 Project presentation: Week of May 16th, 2015

Bonus projects

Bonus projects may be assigned and given extra marks. Bonus projects should be submitted within 1~3 days from the date of the assignment. Marking of bonus projects will be rigorous and the given mark will be proportional to

effort done and quality of work

Class policy

Cell phones must be turned off. For expected emergencies, inform the instructor before the lecture begins that you will keep your cell phone in silent mode.

No food or drinks during lectures or tutorials.

Plagiarism will not be tolerated; you cannot submit the words or ideas of others as your own. You must not receive unauthorized help from anyone when solving assignments,

writing reports, or solving exams and quizzes. ( )

Students who miss a midterm for a valid excuse (e.g. medical necessity or family crisis, subject to approval by the course instructor) will be offered a makeup exam at the end of

the semester.

Anyone who misses a midterm without a valid excuse will get a zero mark in this midterm.
