linearization of radiative energy source term
A question about linearization of radiative energy source term ? So that it can be incorporated in a CFD code (SIMPLER ALGORITHM).
S=ka(4EB-G) to be used as a source term in the energy equation Where ka=absorption coefficient
EB=blackbody gas emissive power
S can be linearized as
S= SU + SP x (Variable under consideration? enthalpy or intensity)
What will be the expressions for SU & SP and the logic behind them?
thank you for your time
