Fun article to read but using incompressible flow as an assumption is extremely dangerous. The main effect of the assumption is that density does not change which is not the case for airfoils, particularly near the wake which usually ends up as P_0 (ambient pressure). It would be even more awesome if the author left NS in it's standard form and add the new deep learning PDE solvers [1]. [1]https://arxiv.org/abs/1708.07469 https://arxiv.org/abs/1708.07469
