GRADING and EXAMS:
Grading will be based on your performance in the assignments, presentation of a term paper and a final exam.
Broad goals of the course
Course description This is a graduate level course in fluid mechanics dealing with fluid systems dominated by surface tension. The course will outline the governing equations and boundary conditions and cover a variety of interesting phenomenon in free surface flows. Attention will be given to drops, minimal surfaces, thin films, Marangoni effects, coating flows and contact line dynamics. The course will also include reading assignments on seminal research papers in interfacial flows.
List of topics to be covered:
Introduction to interfacial flows - Governing equations and boundary condition - Laplace Pressure - Minimal surfaces - Young's law - Fluid statics - Hydrodynamics of Interfaces: Thin films, RayleighTaylor instability, Plateau Rayleigh instability, Drop oscillations, coating flows, Marangoni effects - Contact line hysteresis - Dynamic wetting phenomenon.

Useful suggestions and course policies:
You are strongly advised to sincerely work out all the details of your class notes again at home. You use the same mantra for your assignments as well. If you don't take your assignments seriously, you are very likely to face great difficulty in solving final exam problems.
Notes: You are fully responsible for taking all the necessary notes during class. I cannot promise to provide you with any hand-outs.
Assignment: Assignments are to be submitted before the class begins on the due date. Failing to submit an assignment will normally result in a mark of zero. Exceptions may be granted in two cases: prior consent of the instructor or a medical emergency. In the latter case, the instructor must be notified as soon as possible (preferably before the day of submission), and presented with a doctor's note immediately upon the student's return to IITH.
