hi formers
i am modelling a room with negative constant heat flux in windows
i want to use this boundary condition
windows
{
type turbulentHeatFluxTemperature;
heatSource flux; // power [W]; flux [W/m2]
q uniform -40.8; // heat power or flux
alphaEff alphaEff; // alphaEff field name;
// alphaEff in [kg/m/s]
Cp Cp0; // Cp field name; Cp in [J/kg/K]
value uniform 295; // initial temperature value
}
my solver is buoyantbossinesqueFoam
but in this solver alphaEff and cp are not calculate....
what can i do?
thanks

Hello,

you have two options

1- modify ur solver
2- use groovyBC

to use groovyBC, you need to set temperature gradient which is heatflux divide on conductivity
