Simulate Additional Pressure Drop

szhou02 · December 11, 2018, 04:19

Hi everyone,

I am modelling a pipe system with an additional appliance and measuring the pressure drop In the system and particle flow rate. At the end of the system, there is a appliance that causes the pressure to drop. However, Its hard to model this appliance within fluent. Is there a way to simulate a pressure drop in the system using fluent?

I forgot to mention. The pressure drop is known at 500 pascals

What are your current boundary conditions? You are not modeling the appliance anyway so it really doesn't matter that 500 Pa magically disappears somehow outside the domain...

Imagine we all have pipes, but the pressure drops to 0.032? Pa in interstellar space. No one is in a hurry to model this effect in our CFD.
