Computational Demo: This is a series of videos to introduce students to computational fluid dynamic techniques. I coded a viscid solver to solve 2D RANS equations in a Cartesian domain. The program, called cavity.f, is written in fortran and I use Matlab/Octave to post process.

The code follows the derivation outlined in the book "Fluid Mechanics" by Kundu, Cohen and Dowling in the Chapter entitled "Computational Fluid Dynamics", which is on page 453 of the 5th edition.

As in the example in the book use a Mach number of 0.05 and Reynolds numbers of 20 (no shedding) and 100 (with shedding).
