Model for Liquid-Solid multiphase?
 

Dear all,

I am new for multiphase simulation.

I would like to simulate relitively large particle in fluid channel. The size of channel is 30 micrometer depth and 300 micrometer width, and the length can be is very long, ~10cm. There are many small outlets on the channel before a main outlet at the end of channel.

Fluid is water. Particles are around 15~20 micrometers (Very close to the size of channel depth(30 micrometer).

Could you please advice me what model do I have to use and whether meshing particles is neccesary or not?

Deeply thank you for your answer.
