Hello all. Please help me with using the BC "externalWallHeatFluxTemperature" with the solver "fireFoam". The problem is that thermophysicalProperties must be hePsiThermo (the solver does not permit other) but kappa needs solidThermo. The version of OF is the latest. Does this solver permit to use the layers with virtual thickness? If not please show the ways of arranging obstacles with the temperature that rises during the fire. Thanks.

cant you use lookup?
Is this BC is possible to use in enthalpy equations as well? Thanks. |

Hello. Now the question is not in writing BC. There is an equation in the file externalWallHeatFluxTemperatureFvPatchScalarField. C:
q = (Ta_ - Tc)/(1.0/h_ + totalSolidRes); This is the eq. of steady state heat transfer. It does not make sense in fire modelling. One must solve the eq. of unsteady heat transfer inside solids (Fourie eq.). Does OF have such opportunities? |
