Hi All,

Is there a way i can model both air and oil in CFX? I have defined both as separate domains and defined the oil as a new material. But i am not able to select only the oil and only the air. When i select for one domain, the same material appears in the other doman. Is there anything i am doing wrongly? The oil pipe is within the air Domain and would defining it as a subdomain make it to work?

Thanks!
Jimmy

Yes, and there is many ways of doing it: eularian multiphase, free surface models, oil droplet/air bubble particle tracking and many more.

But from your description you seem to have air in one domain and oil in another. Is this correct?

Yes, it is correct. I am looking at inlet air to a compressor and we want to use the inlet air to cool oil that is located in pipes at the inlet. In short I need to do conjugate heat transfer simulation.

I used to simulate combustion and would in that case define an air inlet and oil inlet as well.

I need to look at the tutorials again to see if I can figure a way out.

Thanks as usual for your support.

James
