chtMultiRegionFoam solver application for high velocity& High Pressure
Have anyone tried the chtMultiRegionFoam solver application for high velocity& High Pressure?
I was using the cht heater tutorial.
when I increased the bottom air velocity (~100m/s) and pressure (~10 atm), I got the error massage after several iterations.
Anyone can help?
thanks a lot!
your topic is really interesting also for me.
I think one of the problems could be connected with the Mach 0.3 and the formulation of energy equation:
Which version of OF are you using? (the last release has quite big differences in energy balance)
You could try several options:
1) replace hRhoThermo with hPsiThermo
2) modify the SIMPLE algorithm to SIMPLEC
3) check which h-Eqn is implemented: you could include the term of viscous dissipation
BTW which is your Re number:laminar or turbulent?
I am using the newest version of OF. And I tried both turbulent and laminar case.
I will try as you suggested. Thank you again.
