Among below threads, see the title "modeling of coupled problem". As I think, that could be a solution to your situation.

Thanx Chiseung

But I still have a problem; my task ivolve exothermic reaction which should be intiated by a heat from inner pipe inorder the reaction to take place; so according to your suggestion It is not yet clear to me how I can achieve this exothermic reaction in my process....
