Nice to meet you

Can you please make a video on how to write UDF for DEM and Coupling with CFD ?

Would it be possible for you to provide me with a comprehensive tutorial on this subject? Your assistance would be greatly appreciated.

Hi, I want to simulate a cyclone as a 4-way coupling. Please help me

That's a nice simulation. You were really ahead of the time. I made a tutorial for a coupled simulation of openFoam and liggghts. It includes also a simplified classifier. If you like, check it out. kzbin.info/www/bejne/fqS3g555aqp8hdk

As you have made axial, tagenial, and radial velocity contours in paper. Can you kindly elaborate how to made them.

Separator?..where is gas phase?...I look one phase just going down.

Sir can I get this full tutorial of this videos please post it

How do I get this software with training?

Can you upload cyclone separator cfd-dem coupling case

what is the variable used in tecplot??

i have studied your paper. Nice solid flow pattern video.

Dear Dr. Chu, May I get your email address? I am a student of the University of Queensland, Australia.

Could you please help me about the initial height by Patching of Particles in DDPM or DEM in ANSYS Fluent?

Sir, how did you calculate the superficial gas velocity?

Hi! I´m trying to simulate de efficiency of a cyclone I design for college, and I just read you used ansys for this. Do you know where I can find how to configure properly the model to do that? I´m very begginer with Ansys and I´m having a lot of doubt about how to do it. I were looking for tutorials, books, and practicals examples with no luck. Thanks

Actually i want to understand what is meant by loading rate??

Hi mate, your video is very interesting. Could you please give me some advice " How to model this kind of the reactor in the ansys program" If yes how can I contact you. Thank you

Which software you use for simulation?

Hi Kevin, nice simulation. Can Fluent display the particles like in your movie?

Hi, but i donot think Fluent will recognize Fortran codes. Cheers, Kaiwei

Hi, basically you declare all of the subroutines in a header file (*.h), then you include the header file at the beginning of all of your source codes. Finally you load the source codes into fluent and compile them, which will generate a file of *.libudf. Cheers, Kaiwei

@itsbigdan Fluent with our own DEM code is used.

@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,

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...

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.

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.

Our method is very similar to EDEM. It is ture that we have a quite long UDF for Fluent. Cheers and thanks!

You are welcome! All the best to you too!

Well, I donot know much about absorbtion/desorption. But I do know Fluent can simulate lots of chemical reactions. CFX is even better than Fluent in the simulation of chemical reactions. Cheers,

Yes, it is true. Segregation is unavoidable in this CFB. By the way, higher fluid velocity will suppress segregation.

Very usuful simulation. I was thinking in the posibility of mixing and dry sand and cement by this way, but it seems that could be segregation... Thanks a lot.

Thanks and Cheers, KaiWei

Yes, you can borrow it. Just remember to say it was created at UNSW by KaiWei Chu, Bo Wang and Aibing Yu.

Thanks alot. I will check the papers.

We couple our DEM code to Fluent. There are some papers available for detailed information. CHU, K. W. & YU, A. B. (2008) Numerical simulation of complex particle-fluid flows. Powder Technology, 179, 104-114.CHU, K. W. & YU, A. B. (2008) Numerical simulation of the gas-solid flow in three-dimensional pneumatic conveying bends. Industrial & Engineering Chemistry Research, 47, 7058-7071.

Great simulation. Which software is used?

Thanks and cheers!

good work

Thanks and Cheers!

amazing simulation
