I have written a code for solving unsteady 2d compressible viscous flows with WENO5 schemes and looking for simple test cases. I have checked the inviscid case solving 2d Reimann problems and have acceptable results. Lid-driven cavity isn't a good option as the benchmarks available are for incompressible flows. I dont want to solve over 0012 airfoil as setting up the grid itself would take a lot of time. Please mention some test cases along with reference papers to test run my code.

Some problems you can try with a weno code on Cartesian grids

These two have smooth solutions but good to test code since they have exact solution:
Plane Poiseuille (density is constant)
Plane couette (constant pressure, variable density)

Shock-boundary layer interaction: google this

A vortex roll-up test, incompressible but good to test weno scheme since vorticity develops sharp gradients, you can try this at low mach number.

There are some testcases on:

(pisoCentral, QGD, hybridSolvers)

Some of the cases are described here:
