heat transfer at the entrance of a channel using the turbulent model

Hi,
I'm trying to model a fluid in a rectangular tube with a heat influx on the top. I think the model is not right because I get higher temperatures at the entrance of the tube, indicating lower heat transfer coefficients, when normally the entrance temperatures should be lower because the heat transfer to the fluid before the temperature profile is established. I upload the file of the model. Which one is the error in my model?(I'm using the k-epsilon model)
Thanks in advance,
Ann Jenkins.

Hi,
Sorry I didn´t upload the model.Here it goes...where the temperature is higher I define the inlet of 0.8 m/s. I´m using the 3.5a version.
Thanks,
Ann
