Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...

The solution to your problem is not with the negative values.

The solution to your problem lies in the trend reversal between the 3 figures for inlet pressure.

Bad formula did this trend reversal

fix simple maths mistake my friend

If I may joke, if your device is vertical, there are occassions when increased flow starts syphon effect, lol

Amr Kaood

Which math mistake do you speak about?

Thank u

Is it fixed?
