Parameters of Large Eddy Simulation(LES)
Dear developers, Sorry to bother you again. In code_saturne 7.0.4, I noted that the parameter of LES is different with other sovlers like charLES or some reference[Pope 2000 Turbulent flows] about LES. More specifically, the computation for filtered size is that, delta = xfil *(xa*volume(iel))**xb, ...

Parameters of dynamic model in LES
Hello, In code_saturne 7.0.4, I noted that the parameter of dynamic model in LES is different with other sovler like charLES. More specifically, the equation delta = xfil *(xa*volume(iel))**xb where xfil defaults to 2.0, xa to 1.0, xb to 1/3, which is different with other sovler that use xfil to be ...

large eddy simulation with combustion(idilat)
Hello, In code_saturne 4.0.2, I tryed idilat = 1, 2, 4 for LFR(laminar finite rate) combustion model with dynamic LES and idilat = 1 for k-omega SST URANS in a CH4&H2/air bluff body flame. The results are quite different. In URANS, the time-average temperature in the flame are about 2000 K, but ...
