Hellow, all.


I want to see a simple heater. I try to set its, but always get "failures".

I set the flow 1 is water, the flow 2 is air.
The water flow in a cupper tube, and air flow outsize.
The air doesn't mix with water.
Both they have velocity, the axis of air velocity is Z , the axis of water velocity is X.
Air temperature is higher than water.
I set one block for this system, should I?

Does someone can solve this problem ,or have better ideal and method?

Thank you.

Sorry, I have poor english.

Sounds reasonable. Are you resolving the tube thickness all right so that the fluids do not mix? What kind of failures do you get?
