inlet pressure not conform measurements

wouter · February 1, 2011, 18:29

I used simpleFoam to calculate the inlet pressure of a nozzle.
I set the inlet water velocity and I hope to verify the necessary pressure to get this flow through nozzles of different configurations. For one configuration I have measurements of this pressure. OF gives me pressures of 300 N/m2 while 0.2 bars =2000 N/m2 is measured

In another post I found the solution to my problem.
I have to multiply the calculated values with the density of the fluid (1000 kg/m3 for water). Now the calculated values are in accordance with the measured values.
