Turbulence generation for particles
 
Hallo



I'm working on a model to describe dust explosions in OpenFoam and the turbulence model fails. In the flame front the particles were accelerated, and after that they slow down. For that reason I have high relative velocity they should have an impact on the turbulence (k-eps) model. I'm looking now for Papers on that topic, but can't find anything.


If somebody know a Paper about that pleas post the name of that Paper

To tell the truth, I think that particle dynamics can not be studied while using a RANS/URANS formulation...

I have something like a generation therm for k based on the relative velocity in mind. I thought about it, and a additional shear stress could be modeled with the relative velocity and the concentration for the mean particle distance.
