Hi,

I am modelling a cross flow over circular finned tube heat exchanger on FLUENT however, when I change the finned tube wall temperature my pressure does not seem to have an effect on the pressure drop. I am not sure what I am doing wrong but I have created an iso-surface at the first finned tube and at the last finned tube and take the difference of the pressure at the locations to get my pressure drop.

I am using standard k-epsilon model with enhanced fin wall treatment.

Can anyone please enlighten me?
