porous media
HI:
I am very new in CFX and I need to simulate a pebble bed reactor by using cfx5.7.1. I think I have to go for porous media approach but I don't know how to simulate porous media in cfx. Could you please provide me some information regarding this. Thanks a lot in advance. regards... Kamal Hossain |

Hi,
Take a look at Tutorial 10 "Flow in a Catalytic Converter", where the catalytic converter is modelled as a porous media. Regards, Rui |

HI Rui:
Thanks a lot. I have seen Tutorial 10, they used directional loss model. Could you please inform me how can I use Darcy Model instate of directional loss model? Thanks a lot... regards... kamal |
Re: porous media
Hi,
If you go to CFX-5.7.1 Master Index and look for Darcy's law, you'll find a link to CFX-5 Solver Theory, Basic Solver Capability Theory, page 57. If you search the word "Darcy" in the documentation pdfs, you'll also find some information in CFX-5 Solver Modeling, Basic Capabilities Modeling, page 27. Take also a look at this post: http://www.cfd-online.com/Forum/cfx_....cgi?read=6013 and to the replies to it. If you have access to the CFX-Community web site, take a look at: http://www-waterloo.ansys.com/cfxcom...a_in_cfx-5.htm I think in CFX-5.7.1 (and probably CFX-5.7) there are some options which weren't available in CFX-5.6, but I'm not sure. I can't help you further as I never work with porous media. Regards, Rui |
Re: porous media
Hi Hossain,
You might also look into doing this as a multi-phase model. There are specific models for packed bed reactors in CFX. Regards, Robin |
