temperature of fluid

temperature of fluid

temperature of fluid

(OP)
hello all

i am trying to analyze a heatsink with forced convection. as a start i am considering only two fins and the space between those 2 fins. for the fluid in the channel i specified inlet velocity (2m/s) and temperature (300 K). i also specified some heatflux at the bottom of the heatsink base.

after the analysis is over, i plotted the temperature contours and found out the the temperature distribution on the fins is acceptable. the proximal end of the fin being cooler that the distal. but the fluid temperature stays at 300K. Also plotted the sectional view. but fluid temperature is 300 K throughout. Fluid temperature will also increase. But why is it not showing. Any hints?

Mahesh.
