In multi-species modelling without reactions, how does fluent calculate the default value of Diffusion coefficient?
For instance, I have a case with water vapour and Nitrogen, if I choose the "constant-dilute-approx", the default value is 2.88e-5. What is the accuracy of this value? How is this calculated? Will it be any better if I use multicomponent method? Any help in this regard is greatly appreciated! Even links/references would do. Thanks |
