heat transfer modeling

i want to model the heat transfer in the pipe. in this problem high temperature fluid is flow through the pipe and low temperature fluid is flow outside the pipe.

how can i set up this kind of problem in fluent.

Re: heat transfer modeling
I haven't run any H/T myself but I know Fluent has ample documentation of this topic in the manual. That would be my first place to start.

It's very easy. Just read the user manual or read the Tutorial.............

Re: heat transfer modeling
hi there, i go through tutorial and i set up this problem as discribe below. - there are two domain one is for fluid 1 say water which is flow through pipe and other is for fluid 2 say air, which is flow outside of pipe. - in boundary condition there are water inlet(velocity and temp of water is specified), water outlet(outflow), air inlet(velocity and temp), air outlet(outflow), and wall(shell conduction with 2mm thickness of wall, coupled)

but i didnt get satisfactary result i.e. as i seen from result file heat is not transfer from water to air through pipe wall and temperature of air remains same through out the domain.

please help me..

Re: heat transfer modeling
I think you may get some help from userguid bellow. See the section "Modeling Heat Transfer in Two Separated Fluid Regions"

I hope it will help you...

Re: heat transfer modeling
i follow that tutorial but i didnt get satisfied result i.e. though flow in two seperated region is conversed but temperature didnt transfer from one fluid to other fluid.
