Circulating fluidized bed

There is axial solid segregation that large particles are mainly in the bottom part of the bed and small particles in the top part of the bed. By Kaiwei Chu and Aibing Yu. Copyright: UNSW

The CFD DPM simulation work is g8. I appreciate you. May i know your email id ...

how did you couple your dem code with fluent? Is there any way to call consequently dem and fluent? Did you use a batch command? Have you some guide or how to? thanks...

[lazysunleo]

@d3rf0 Yes, you can run cfd and dem consequently by calling dem in the user defined functions of fluent. I do not use a batch command. I get the variables from cfd using udf and share them with dem by use of public variables. You can also put some of them into udm in fluent and then you can view their values in the postprocessing windows of fluent. cheers,

so this is how u make a DIY fluidized sand bed filter...right?!?!

>:O!

[lazysunleo]

Yes, it could be a DIY simplified circulating fluidized bed in computers. Some researchers also think it is virtual experimentation under idealized conditions. In essence, it is a mathematical description of the flow based on first principals.

Our own DEM and coupling codes with Fluent for the sulution of CFD.

what program did you use?

[lazysunleo]

Hi, 4agrees, it is a long-term plan to include heat exchanger and heat, mass transfer in the simulation. We have to try it first. I guess it should work by 50% chance at the moment.

lazysunleo... can you develope the simulation including External heat exchanger?, this attending the traditional design (after the cone valve, below the cyclone)
