I want to know who has experience in using macro DEFINE_HET_RXN_RATE( name,c,t,r,mw,yi,rr,rr_t)?
I have such a problem: In the help document of FLUENT, the illustration of variables mw and yi confused me.
real mw[MAX_PHASES][MAX_SPE_EQNS] Matrix of species molecular weights. mw[i][j] will give molecular weight of species with ID j in phase with index i. For phase which has fluid material, the molecular weight can be accessed as mw[i]. real yi[MAX_PHASES][MAX_SPE_EQNS] Matrix of species mass fractions. yi[i][j] will give mass fraction of species with ID j in phase with index i. For phase which has fluid material, yi[i] will be 1.
An example is shown in help which is about simulating evaporation or condensation on the surface of droplets and there are such two sentences
You all know, in mixture setting, we can arrange the order of species. Default id for the first specie is 0, but for phase setting, primary phase id obviously is not 0 but 2. So I am confused about. I hope someone can help me.
