Aims
Advanced topic in fluid flow is presented, specially analytical and numerical methods. Inviscid fluid flow is modelled using complex variable functions; viscous fluid flow is modelled using boundary layer approximation. Numerical algorithms using finite differences and finite volumes discretization are presented.
Content
1. Continuum media equations. Inviscid and viscous fluid cases.

2. 2D potential flow of inviscid incompressible fluids.

3. Conformal mapping method. Principles of profiles theory.

4. Thin wing theory.

5. Compressible fluid flow. Steichen equations. Analytical methods for the non-linear system approximation.

6. Finite difference schemes. (explicit and implicit). Diffusion equation.

7. Incompressible viscous fluid flow. Dimensionless variables.

8. Large Reynolds number case. Boundary layer equations.

9. Small Reynolds number case. Stokes’ system..

10. Finite volume method.
