Filippo Maria Denaro

Could you better elaborate your question? Do you consider the inertia in the particle equation and using the Maxey equation? The concept of eddy diffusion is related to the modelling of the unknown tensor in the momentum equation, how do you think to include it?

Ilhem Bouderbala

Hi, I'm working on the motion of particles in the water column having low Reynolds number.

Ok, what model of particle are you using? Why do you think a modelled eddy diffusion should be introduced at low Re number?
