Euler solution, NACA0012, Mach = 2.0, AoA = 0

Similar to my previous video, except at Mach 2 and AoA = 0. These are some of the first tests for a CFD solver I’m working on. Eventually it will be implicit, viscous, turbulence, time-accurate, maybe 3D, etc. But that will be down the road, because I’m just working on this for fun in my spare time. You can see small oscillations moving around in the solution because it is 2nd-order with flux limiting, and the values of the limiter tend to change around periodically, preventing full convergence to steady state. Freezing the limiter normally fixes this but might make it less stable (hence one reason why an implicit scheme is needed).
