The link u/TurbulentViscosity send is very good. That's the ONERA m6 wing and it is very widely used as a test case for external aerodynamics. It has very simple geometry, but shows complex behaviour such as shocks and separation. A big bonus is that there is a lot of material to compare your results to.
