Air compressibility in Flat plate slamming simulatiion

wzhang11 · June 10, 2016, 01:59

Hi All

I am trying to add the air compressibility to flat plate slamming simulation, But I have a few knowledge about this

, I am not sure should I use idea gas or user defined EOS, also I am not sure which energy model should be chosen for the Adiabatic compression isentropic process.
anybody have the knowledge about this?

Many Thanks
Jason

Well, you need to use your knowledge of the physics problem to determine this. Is it appropriate to treat the air as an ideal gas with your physics? If so, select ideal gas. If not, you need to figure out what equation of state to use.
