| Each cell's rates are those of its filtered state times the reacting fraction kappa = tau_c / (tau_c + tau_mix) (the partially stirred reactor; Sabelnikov & Fureby, Combust. Flame 160, 2013), with the chemical time tau_c = rho cp T / |q| of the heat release rate q and the mixing time tau_mix = C_mix Delta^2 / (nu + nu_t) of molecular and SGS diffusion across the cell, so kappa -> 1 as the mesh resolves the mixing (Delta -> 0, the DNS limit) and kappa -> tau_c / tau_mix, a mixing-limited rate, where the chemistry is fast. Plain aggregate, captured by value in kernels. More... | |
