Rhie & Chow method/flame propagation?

yang

Hi, there

I just had a problem that the Rhie & Chow interpolation method for the co-located mesh could not work well with premixed combustion (flame propagation) simulation. It tends to over-estimate the velocity field in front of the flame, therefore result in increase of the turbulent intensity.

Does any one know the interpolation method which is able to deal with the combustion?

Thanks in advance.
