Material Removal Simulation
 

Hi All

Does anyone have any idea or have done previously some kind of simulation, where a layer of soil /dust particle is removed by a jet of water ?
I am trying to do computation or want to do the computation for cleaning a surface which is covered with some mud/dust/mineral using some spray nozzle and want to quantify the cleaning effect of the nozzle based on its operating condition. Can someone tell if there is any commercial code or some code which can do this !!

Thanks in advance.
