The sensible enthalpy with reference temperature 298.15K is used in Fluent energy equation. It's completely OK except when phase change exists, becuase of latent heat.
I do not simulate mutiphase model. My model is about vapor with air condensation. the condensate liquid is neglected, and I only need to add mass, energy source in UDF. the total inlet heat flux and outlet heat flux,or others related to heat transfer are calculated mass*enthalpy(sensible enthalpy=S(Cp*dT)), the condensate heat flux equals condensate mass*latent heat. As a result, the energy is no conserved, due to the enthalpy used in fluent not include latent heat. How should i deal with this problem? Thank you very much~ Last edited by Echo; January 24, 2015 at 22:48. |
