reactingFoam temperature drops below bc
I try to simulate (OF-1.7) a oxygen-steam mixture in a cylindrical geometry with two coaxial inlets.
But when I run the case the temperature drops below the initial bc (mixed 385K <-> inlets 403K/638K). Thats bad because at this conditions (p=4.3MPa) the steam condensed.
To eliminate this case I clearly increase the tmperatures at the inlets. But in result the temperature again drops below my default values.
T: fixedValue, zeroGradient, inletOutlet
U: fixedValue/cylindricalInletVelocity, fixedValue, fluxCorrectedVelocity (prevent backflow)
p: zeroGradient, zeroGradient, totalPressure
chemistry and turbulence reaction is off
Can anyone help me?
With best regards
