Does anyone understand the way to derive the energy equation (TEqn) in interCondensatingEvaporatingFoam, which is the derivative solver of interFoam and interPhaseChangeFoam?
Especially, I couldn't understand why the terms of fvm::Sp(---) is added on the left side. What's that? This thesis (https://www.researchgate.net/publica...tion_Phenomena) gives us a good hint, but I couldn't fully understand yet. Some additional explanation is necessary. If you know how this equation is derived, please tell me. Thank you in advance. Shion ANDO |

The Sp term is some stabilisation term. There is some discussion here in the forum about that. If the continuity equation is fulfilled, this term becomes zero.
