What is the definition of Total heat transfer rate for Compressible fluid?
When performing thermal calculations, check the heat balance in the total heat transfer rate [W] through Report->Fluxes. For an incompressible fluid, the definition is:
= ̇ × × ( − 298.15) [ ]
where,
̇: mass flow rate [kg/s]
Cp: specific heat [J/kg-K]
T: face temperature [K]
However, in the case of a compressible fluid (density set to Ideal-gas), the definition differs between the pressure and density-based solvers.
