Fluent / How can I get information about aerodynamic forces and moments (lift, drag)?

« on: August 24, 2012, 09:20:37 AM »

How can I get time-dependend information about aerodynamic forces and moments, like lift, drag, euler angle, CG, of moving and stationary walls in FLUENT?

Thanks.

Fluent / Re: How to get time average tangential velocity in swirl flow.

« on: July 15, 2012, 11:00:23 AM »

You can convert the equation:
vθ = vx cos θ + vy sin θ

into Cartesian coordinate.
x = r cos θ
y = r sin θ

Fluent / VOF to model draining tank, swirling fluid, vortex?

« on: May 13, 2012, 11:16:43 AM »

Hi,

It is possible to model a draining tank filled with a swirling liquid, and to capture the vortex that forms at the drain. The goal is to pinpoint the time at which the first gas reaches the drain.

Please help.

Thanks.
