Modelling sediment pickup of sand pudder (50 µm)

ThomasEnzinger · August 22, 2019, 02:26

Hello,

I'm not sure how to modelling the follow case and ask a "stupid" question

Fluid: air
Solid: sand pudder with 20...100 µm of diameter (spheric approach would be ok)
Description: The solid is placed in an tank. The tank is opened on the top. Air blows and pickup some parts from the pudder.

In my mind, it would be a mixture of Euler-Euler and Euler-Lagrange approach. Euler-Euler for the solid in the tank and Euler-Lagrange for the pickuped fraction.
But how modeling that. How modeling the transition on the surface of the pudder in the tank?

Any ideas?

Best regards,
Thomas

P.S. Avail. Software would be Fluent and CFX

You can start with a Euler-Lagrange approach and see how far you get with this simplification.
