Are there anu 'classical' solutions for two-phase (gas - particle) compressible flows? If not, is there a generic flow case(say flow impinging on a cylinder or something) for numerical validation?

I also concern about this issue. In my case, I am considering of the ghost fluid method.

I am wondering if there is any reliable experimental data available for compressible gas-particle flows.

So far, no such things. I am also finding that but it's pretty rare.
