Hi,

I can't tell how much I'd love to switch to CFD. But CFD seems to be accessible through ANSYS Workbench. And I cannot access CFD through Workbench, although I can model and mesh the geometry....

Hi there,

well now, thanks for the quick replies and the guidance, so far I solved the problem.

But only on laminar basis.

My Re-number calculations tell that my flow becomes turbulent,...

Hi,

Kn lies between 0.0037 and 0.0008 (gas flows through a pipe with 2 diameters). Literature states that with these Kn flow character is viscouos, so a distinction between laminar and turbulent...

Hi there,

it is a vacuum chamber with a butterly control valve and a pumping system.

The gas enters the chamber by a magnetic valve.
The control valve can compansate the pressure increase by...

Hi there,

thanks for the answer.

I made two simulations w. 2 different ref. pressures:

1st simulation) 101350 Pa,
2nd simulation) 60 Pa ref. pressure.

I applied the pressure to all...

Good morning from Germany,

thanks for your reply.

The pressure is not just at the in- our the outlet. The whole tube is pumped down to and held at 60 Pa during the gas flow. Do I have to set...

CFD-problem in ANSYS

Dear all,

I'm new here (and to Ansys), so let me say "hi" to you all.

I just started using Ansys to model a gas flow under reduced pressure conditions for a simulation chapter in my PhD-thesis....
