 November 7, 2005, 12:17 Pressure drop #1 Madhukar Rapaka Guest   Posts: n/a Hi I am simulating the flow(2D) in a fin and tube heat exchanger. (The geometry consists of a long rectangular tube with three rows of cyllinders placed perpendicular to the flow) I want to calculate the pressure drop between two surfaces. Can someone tell me , how Fluent calculates the pressures. I have gone through the User's guide and i found that fluent applies some corrections in calculating the pressures.(Ptot.=Pop.+Pgauge) I am using incompressible flows. So can anyone tell me how Fluent calculates the pressures. thank u

Don't get confused with static head,static pressure those are completely two different parameters in fluent.Hope it clears you.
