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 up 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.
Hi
Apart from the granular flow modelling technique, I was looking at the physics of this problem. I found this paper which shows minimum particle concentration in the core of the double vortex formed at the bend.

Thanks for your answer. Viraj.
but in my problem the cross section of microchannel is rectangular and the flow is laminar. not turbulence.
