Hìr0 New Member Luigi Join Date: Apr 2011 Posts: 10 Rep Power: 15	Hi, I would to know if combustion occurs at constant pressure in ReactingFoam? I'm confused looking at the code, I don't understand the logical sequence in this model. 0(internalField: p0,T)0 -> reactions(therm_dat.chemkin.inp):Yi,Ti,hs -> GasPerfect: psi=1/RT -> basicPsiThermo(p const):rho=p*psi -> hmix=f(hs,psi) -> then how updates p at next time step...solving p equation???? which is the difference with rhoReactiongFoam? Please help me!Thanks
