now i have a problem: i want to run a simulation, high speed(0.3Ma)gas flow over the surface of powder bed(d=6μm).I am a beginner of CFX, and didn't known which software can solve my question? thanks!

Hi,

But what are you trying to model? The pressure drop? Whether the powder gets picked up by the flow and where it goes? You will need to be more specific.

thanks, In my problem,the powder will be picked up by the flow ,i want to know how much the powder will be picked up by wind which speed is constant.

In fact, i want to devise a machinery which can fluidize metal powder, and i want the flux can be control by the speed of flow. The high speed wind which may be supersonic blow over the surface of powder bed. And have the question what i expound above.
