Moving reference frame for a particle in flow

supermanks · August 20, 2016, 18:57

Hi all,

I have a conceptual question which shouldn't take up too much of your time: I'm working on modelling the flow field around a finite-sized body which is being translated and rotated by a fluid (which is pressure-driven) . If I'm looking to model the steady-state situation (for both particle and fluid), can I get away with using a translating frame of reference alone, or would I need to use a rotating frame as well? Also, why?

Any quick ideas? TIA!

Regards
