If you're interested to learn more about aerodynamics I would highly suggest learning a bit of classical aerodynamics. It will not be software oriented, since most of the theory deals with approximating very complicated behavior with simple analytical models.

It could be interesting to do a comparison with finite volume methods to see when/how those approximations break down.

Totally newbie question - 'approximating very complicated behavior' - this seems like a perfect problem for ML to me. Is this something that's used or explored ?

It's absolutely being explored. There is a lot of active research into using ML to learn solutions of PDEs (Navier-Stokes in this case). It's not my field so I don't know much about the specifics.

The works that I've read train an NN on numerical solutions for different geometries and boundary conditions. Then they try to infer the solutions for configurations outside the training set, which should be much faster than recomputing the numerical solution.
