Flow through concentric pipes carrying different fluids
 

Hello Everyone,

I am beginner at fluent. I have assignment which of course I couldn't solve. So asking here.

Problem:

Flow through two concentric pipes is vertically upwards.
Air at 30 deg. C. flows through outer pipe. Water at 30 deg.C. through inner pipe.

Heat generation of 0.5 kW at the center of inner pipe.
Transient condition.

Assume other required data such as length and diameter (general flow problem).

Show:
1)Draw temp. profile
2)Velocity profile

Please give me the procedure to solve it in fluent.

Refer attachment for the problem description.
