I just wanted to add that mass diffusivity is correctly accounted for in the specie equation:
Code:
fvScalarMatrix YiEqn In OF this becomes under the assumption that and It seems to me that this term is then neglected in the Energy equation. The approximation (if it is neglected) should be ok for Lewis number close to 1, where Lewis number for component i is defined as: where k is the thermal conductivity. Note that Le=1/Pr following OF implementation. Are these ideas correct? Is the the heat flux due to mass diffusion neglected in energy equation? Or am i missing something? Thanks, Andrea |
Hi Andrea,
I have read this part of the code and I think what you said is right. In OF, the unity Sc number assumption is used for specie equation since the differential diffusion model is not available. Gao |
