Pressure Outlet
Hello everybody,
I am trying to model a simple jet flow. Laminar, Incompressible,unsteady flow. At the exit boundary, I specify pressure outlet condition. Is it good to use this condition.Does the pressure outlet condition work the same as outflow condition and extrapolates properties from the interior. Thanks in advance |
Re: Pressure Outlet
Pressure outlet imposes a constant value for pressure or a pressure profile (using UDF) at the outlet.
All other properties are extrapolated from the interior. Hi :) ap |
Re: Pressure Outlet
Hi, I did simulate a jet flow recently: Falling down Water jet into air. Are you simulating it in a confined domain? If it is the case, your jet will attract air by moving and create recirculation zone. Depending on how far from the jet is your oulet, I would advice you to use a pressure outlet with a correct backfow setting.
