Default high temperature plasma burning

Did anyone use CFX for something like following problem? Many phase plasma burning (with chemical reactions) of dispersed solid coal particles or liquid fuel droplets in air (or other) plasma flow. Temperature of the process can reach 4000-6000K. I think CFX can, but I'm not sure about so high temperature burning. Does anybody have any experience? Thanks for your response!

Hi,

CFX does not have the physics to describe plasma flows. CFX has models to handle normal coal or fuel burning, but I don't think they are valid at the temperatures you are quoting (somebody correct me if I am wrong). Also I can't see how coal or fuel could get temperatures as high as you suggest. You must be doing something strange to it to get temperatures that high.

Thank you Glenn for your answer. The problem isn't my. I don't know about details. But in general, it has an ecological direction. It is annihilation of polluted ground by burning-out in plasma (e.g. oil-cut soil).

Hi,

OK, if the temperatures are high enough to make plasma effects significant then forget about using CFX.
