reactingFoam with constant diffusion

c_dowd · April 21, 2013, 02:52

Hi all.
I'd like to investigate the effects of diffusion in a reaction, and to do so I'd prefer to have the species diffusion coefficient as a constant scalar. Is there an easy way to do this or do I need to modify the solver? Ideally I'd like to change the transport model in the thermophysical properties file to const, but this means I have to choose a constant cp thermo model, which I don't really want.

Hi there,

I'm currently looking into doing the same thing within reactingFoam, did you ever figure out how to change the diffusion in reactingFoam
