HEAT TRANSFER in HEAT EXCHANGER
 
Hai, I'm using Ansys 14.0 Fluent to simulate heat transfer in heat exchanger. Earlier i used shell conduction method but i lost at the free stream temperature value. I'm not sure which temperature value to put up. any suggestion please? however i tried with various temperatures, hot fluid temp, cold fluid temp and also average temperature. i think the free stream temperature value highly involve the out come and I'm not sure with the results.

so now I wanted to try use the heat exchanger option - dual cell model. however now im failing to create the overlapping zone. can anyone help me with that? how to create overlapping zone please?
