Coefficients of RAS model for particles in TwoPhaseEulerFoam

Davyd · May 4, 2020, 08:30

I have started simulation of a fluidized bed in TwophaseEulerFoam. It should be mentioned that I am quite new regarding to my work with openFoam. I got the problems when started to consider turbulence Properties for particles. Could someone help me with advising or recommendation where I can find the detailed instruction or guidance how correctly to choose all coefficients for my case and what is the meaning of these coefficients.
I have attached the tutorial file "turbulence Properties.particles" with the values provided.
I can not find this information in UserGuide.

Any help would be highly appreciated.

normally, coefficients for turbulence models are fitted to experimental data.
for more information you should check out the original paper/source.
