Centrifugal Force

Hello guys,

for sure some of you will immediately answer this question. I am dealing with a case where the centrifugal force in fluid flow has a significant impact. So far there is no Problem as I always thought that the tool Ansys CFX does automatically consider the centrifugal force because it arises from fluids inertia. But now I have found some work, where the centrifugal force is implemented by hand into the code of CFX in order to consider it.

My question now is, if this is required or does this lead to an overestimated impact of the centrifugal force?

Thanks for your answers.

Hi, I am studying a problem which the implementation of the centrifugal force in the rotating domain may be important, while also may be misinterpreted in the modeling. Could you please provide the sources you found where ''the centrifugal force is implemented by hand into the code of CFX''?

This could be of great help. Thank you very much!
