Duct Flows
 

Guys,

This is elementary. I want to know that in Fluent to find out the pressure drop across a duct, do you integrate the "static pressure" on the inlet surface or do you integrate the "Total Pressure"?

Plus what is the best tubulence model when I am expecting velocities of 10 -15 m/s inside the duct with air bieng the working fluid.

Your help will be much appreciated.

Cheers

Thanks
