Simulation of a pure-pitching and pure-plunging airfoil with StarCCM+

mtheory · September 1, 2021, 06:43

Hi,

I would like to simulate the unsteady aerodynamics of two different and decoupled airfoil motions: firstly the pure plunging motion and secondly the pure pitching motion.

Is there a way to specify time-varying inlet velocities in StarCCM+ (one for pure-plunge and another one for pure-pitch) so that the interaction fluid-airfoil represents the desired motion? Which equations should I use?

Thanks in advice!

Hi,
You can use user defined field functions to simulate time varying inlet velocity conditions. As for the pure pitching and pure plunging motions, use DFBI and set the DOF accordingly.
