Abstract

The addition of overset capabilities to the multiphase CFD code, UNCLE-M, allows for a more efficient method to model complex configurations. This technology is displayed by modeling two- and three-dimensional hydrofoils undergoing pitch oscillations for various hydrofoils, cavitation numbers, and pitch frequencies. These simulations include experimentally validated quasi-steady and unsteady cases. None of the cases modeled exhibit dynamic stall at single phase conditions, but at decreased cavitation numbers, the stall angle of attack decreases and dynamic-stall effects due to cavitation are captured and appear to be slightly different from the single-phase case. These solutions are valuable for providing additional insight into the entire flow-field. In general the overset approach appears to function well for such dynamic cases.
