Hello all ;
i want to simulate compressible two phase flow(which includes evaporation/condensation and cavitation mechanism) in CD nozzle for analysis EERC system performance.i m going to study with R600a (Isobutane)
I have some question about setup case.I will use pressure based coupled solver but what should i use density type for liquid phase ? i will use polynomal pieciwise variable density until 0.3 mach but after that point should i use compressible liquid density type ? If yes, how can I make it change "polynomal pieciwise density to compressible density" in analysis after 0.3 mach ?
Thanks for all reply
