Interface in a rotating domain

error404 · April 30, 2014, 05:38

Hey CFDlers,

i´m simulating a turbine. I´ve modelled the half of the turbine. Which interface is to choose in a stationary simulation between the blades for example in the rotor. Is there to choose "frozen rotor" or "none". There is no relative movement between the blades of the domain. But there is a movement between rotor and stator.

The red colored is the rotating domain and the blue colored is the "interface".

The rotor is shown on the picture attached.

Thx Simon

Hav eyou done the tutorials which come with CFX on rotating machinery? They explain how to do this sort of stuff.

Thank you for your support.

Is it "OK" for CFX, when the surfaces of the interfaces are really looking different?
