Introducing an injection region in CFX without using in-built point/volume sources

pdhyani96 · January 10, 2020, 19:21

Hello guys,
I am trying to introduce a circular inlet on a blade surface for injection of coolant. Until now, I have been trying to simulate the results with the help of source points.

I tried adding section of circular inlet boundaries in Ansys design modeler. But when I try to export it to turbo-grid for generating mesh, the software does not identify the circular inlet boundaries on the surface of the blade and gives me an error.

Is there a way I could introduce more sections/domains in CFX other than inlet, outlet, hub, shroud and periodic sides?

I am not familiar with turbo-grid so cannot help you with that software. But if you take the geometry into DesignModeller/SpaceClaim you can edit the geometry to have what ever you want, providing you have a bit of solid modelling skills.
