Modelling cohesive particle

colen · October 14, 2010, 09:12

Hi,
I'm trying to model a cohesive material in CFX. I've successfully used it to simulate free-flowing material(low moisture content material) in a gas stream. Now, I've another set of experiments carried out with high mositure cotent solid material flowing through a gas stream. I used Eulerian-Eulerian model for the low moisture content material flowing through the gas stream and I plan to use the Eulerian-Eulerian model for the high moisture content material as well

How can I implement this in CFX?

I look forward to your advice.

This will be very challenging in a eularian-eularian context. Have a look in the documentation under the Theory/Multiphase/Solid Particle Collision Models. Does any of the models presented there help?

Alternately you can go to a particle tracking approach then you can control things like agglomeration and breaking up of particles directly. This will require modelling a represntative number of particles and this can be limiting.
