Fan boundary condition in CFX?
 

Hi
can anyone please tell me how can i implement a fan boundary condition (as is present in Fluent) in CFX?

and also is it somehow possible to implement it somewhere in the fluid domain?

Thanks

The fan BC will just be some function of velocity and pressure and you can impose this as a CEL expression.

There has been plenty of posts on the forum about how to implement fan curves, this may be of use.

Hello Glenn,

I have to model a fan inside a domain in cfx. can you please send the link of post where I can find more information about fan curves

Have you googled fan curve?

Hello Glenn,

I looked for the material available online. I am able to simulate the fan, however my fan is not aligned to any global co-ordinate but is rotated about x axis. So, while adding the momentum term, I should add components in both y and z directions proportional to the angle that fan axis make with z and y axis?

Then you simply work out the components in the xyz axes. This is basic vectors.

Maybe I don't really understand your question, but just in case, you can create additional coordinate system based on your fan and specify velocity relative to it.
