heat transfer through fluids in a pipe in pipe
 

hello all,

can any body help me to find the method in Fluent to calculate the heat transfer through two fluids with different temperatures flowing though a pipe in pipe structue(conjugated flow through pipes).

thanks in advance,

Re: heat transfer through fluids in a pipe in pipe
 

Model the structure, let's say tube&fin heat exchanger. Use inlets and outflow for both the fluids with their inlet temperatures. Solve the problem. See the temperature results.

I think you can check-up by modeling a simple two channel Aluminum/steel block with water flowing in the counter flow with different inlet temperatures.

Hope this meets your requirement. Ashu
