Course Objectives
By the end of this course, the student is expected to have acquired knowledge on:
- Fundamental physics governing the unsteady flows;
- Derivation of the unsteady governing conservation equations and simplifications;
- Analytical and numerical analysis of incompressible steady flows;

- Steady and unsteady incompressible flow about thin wings;
- Moderns subjects such as vortex lift and flapping-wing aerodynamics.
Course Content
Overview of steady incompressible and compressible aerodynamics. Unsteady conservation equations. Potential flow and acceleration potential.
