Hello! I am working in a model for simulate the wind blowing in a desert surface. For the moment I think that the models I can use are: K-epsilon, and mixture model two phase, primary phase air and second phase sand, the second phase granular. Other question is wich must are the phase volume fraction and the packing limit value?

I don´t know how modeling the behavior the sand particles into the air. I only modeling the saltation model of tranport. I read something DPM and langragian but I don't understand fine.

How modeling the trayectories of sand particles and his erosion in the surface and the sedimentation process?

Someone knows how it do?

Thanks!
