(*https://www.cfd-online.com/Forums/fluent-udf/121694-convective-term-uds.html*)

Convective term of UDSFluent solves the convective term of species transport equation as
∂(F_i φ_k )/(∂x_i ) where φ is the kth scalar, x_i is the space coordinate, and F_i is the user defined mass flux which is calculated as F=area intg of(rhoV.dA) rho=density, v=vel vec, dA= area vector the F or the mass flux that it calculates is the mass flux of what, the scalr phi or the fluid. thanks in advance |
