I am trying to add enthalpy source term to the Energy equation. I have discretized the term and tried to bring it in the form Sp*T+Sc.
The enthalpy term is -ρAL⋅(𝜕𝑇/𝜕t)
where ρ = density and AL=constant and T = Temperature
I have written the UDF ,it's getting compiled but not giving proper results.
I am new to UDF . Can someone tell me whether it's correct or not. I have attached the file below.
