Hello to everyone.

I'm developing a fully-compressible Navier-Stokes solver and I need a simple numerical test in order to debug a my two-dimensional solver.
Can anyone tell me if there is a test (something like Poiseuille for uncompressible flows) even for compressible flows?

Thanks in advance.

It depends on the goal. If your code solves low Mach problems, use the Poiseuille problem as reported in the jcp paper of Poinsot & Lele. A different issues is if you want to assess solutions with shocks.

I deeply tested advection therms and now I need to test if viscous solver is properly. Can you suggest me something?

Thanks

Poiseuille steady solution if your code works on low Mach problem and the Taylor solution for the unsteady problem
