CFD final exam

Lid driven cavity

The first simulation regards a 2d lid driven cavity with different Reynolds. Results are compared with C. T. Shin, U. Ghia, K. N. Ghia., “High-Re Solutions for Incompressible Flow Using the Navier-Stokes Equations and a Multigrid Method”. In: Journal of Computational Physics 48 (1982).

Poiseuille flow

Then I implement a Poiseuille flow in 2d, comparing the obtained horizontal velocity along a vertical line with the analytical solution.

Airfoil

Boundary layer

To look at how the Reynolds number and $x$ act on the thickness of boundary layer, I run simulations on the foil with different $\nu$.

Recirculation

At this point I look at the effect of recirculation on the foil when tilting it.

Bernoulli equation

In the end I test the validity of Bernoulli equation.
