Hi CFX users,

I am interested in knowing if CFX and Fluent has been benchmarked for heat transfer problems. Which software provides better solution and provides higher productivity (ease of use, solver and parametric studies)?

I am interested in heat transfer in a rotating equipment with convection from fan air flow.

Thanks in advance for your suggestions.

Thanks, Ashutosh

hi A.Joshi!! I am working on CFX exactly for th same issues. I think that CFX is a very good solution to study rotating system with convection from fan air flow. It provides very good productivity even if its very difficult to make local studies. I studied air flow cooling of power generators.

Let me know if u have any questions about CFX for the heat transfert study in rotating equipments.

Thanks Alex, How do you model Fan in CFX? Represent as momentum source or fan object??

Thanks, Ashutosh

Hi Ashutosh, u can model it as momentum source if you know the curve "Q vs pressure". u have to know that the "pre rotation"( = shirling in front of the fan's air inlet) effect are very important. In fact, it could midify the fan curve. SO, to take account for the shirling effect, u have to represent the fan in yor 3D model.

Are you working on power generator model? For a company? Do u use CFX CFD software or Fluent?

Thanks!
