reactingFoam temperature drops below bc
Hi foamers,
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. BC: (in,wall,out) 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 pit |
