how to set particles at bottom in a fluidized bed
Hello
I am simulating a gas-solid flow in a fluidized bed with Eulerian-Eulerian mixture model. I hope the particles are set at the bottom of the verticle flow field in initiation, but do not know how to do that. I just know how to set the volume ratio of the 2 phases, then the solid partcles are distributed in the whole region evenly. Thank you in advance! B |
Use Patch

I am doing similar problem. I am not sure if you handle your problem. You can use Adapt and Patch to initialize. The details you want are introduced in Tutorial, I think it's about Eulerian model and heat transfer. Besides, I do fixed-bed simulation, but the results are of divergence, I still don't know why. And a friend of mine whose name is Chetan is giving me aome advice. I do not know what is going on with your problem now. Expect contact with you. |
Hi Friend
I think Patch is the right way to solve it. And I tried Star ccm with User field function to define the initial distribution, with the language in Starccm called Syntax. I am also new with simulation, You may tried to modify the parameters that are limited during iterations. We can keep in touch. Quote:

I have not involved in User Filed Function. I think when I finish undergraduate thesis, I can have plenty of time to study. I frequently use the e-mail whose id is liufengustb@hotmail.com You could send me to your e-mail into my e-mail. Best regards |
