Gravity effect in Fluent

August 7, 2007, 05:23

Hello everybody, I'd like know how the effect of the gravity is introduced in the simulation of a flow in a vertical pipe? That so, the pressure computed by Fluent is p+ro*g*z or only p (in the Navier-Stokes´s equations). Is there a difference between the simulation of the flow in a vertical pipe and in a horizontal one regarding the setting of the gravity in Fluent? Regards, Chouki,

already u r using ro*g*z(it will include gravity effect also), then why r u thinking ....
