SL_ST Two-stage Cyclone Separator

These are the results of my modeling hobby. I am not an expert in gas dynamics. I'm just trying. It has always been interesting to check the behavior of such a system. In general, this is not the first iteration. If you like it, I will continue to further improve this design.

Here you can find some CFD:
