I had been working with the buoyantFoam solver. I have succeeded in implementing buoyantFoam solver with SIMPLE Algorithm. Now I want to add species transport equation to the buoyant Solver.
On way, I stumbled upon the rectingFoam solver where a generic species transport equation is implemented in $FOAM_SOLVER/combustion/reactingFoam/YEqn.H Can someone please explain how this implementation takes care of change in enthalpy due to species transport? My first impression was that the implementation was faulty, but I later realized that the in the createField.H file, the implementation of species also include the enthalpy of the gas. ################################################# combustionMixture& composition = thermo->composition(); PtrList<volscalarfield>& Y = composition.Y(); word inertSpecie(thermo->lookup("inertSpecie")); ################################################# Further, in the YEqn.H a new convectionScheme is inherited from the "fv" class called mvConvection, which defines Yi_h. So, somehow the enthalpy is included in the implementation but is very elusive to my inexperienced eyes. Can someone please help me understand it better? (**The implementation looks very native to hCombustionThermo.) |
