Fluid-Structure
Interaction: Rotating
disc and plate
This
example shows the simulation of a rotating plate and a rotating disc in a tube.
Due to
the high fluid velocity the flow is modelled:
-
Fully
compressible
-
Turbulent
(RANS)
The first
example shows a 2D simulation of a plate, which separates two chambers
each one of them having different pressure. The plate is opened suddenly and the pressure
compensation takes place. The particle tracking visualizes the high speed
flow (Ma 0.7) during the period of pressure compensation. Due to the high acceleration of the
plate, inertial forces also cause stresses in the
plate.
In the 3D
model a disc rotates in a tube (turbulent, fully compressible flow).
Problems with large
rotations can be realized in 3D analysis as well. |
