Hi everyone..... I want simulate granular flow (liquid-solid) in curved microchannel by Ansys Fluent (Euler-granular model) that cause to create most particles concentrated at the center of Dean vortices. But in my simulation at the center of Dean vortices, particle concentrated or volume fraction of second phase is minimum. How can I setting details in fluent for achieve to this purpose?
particle diameter range is 1.8-5 micron.
particle volume fraction range is 0.0006-0.15.
no slip condition in channel walls.
Re=450.
