Numerical Investigation of Nonisothermal Cavitating Flows on Hydrofoils by Means of an Extended Schnerr-Sauer Model Coupled With a Nucleation Model

摘要

This paper presents a numerical investigation of cavitating flows by considering the nucleation effects in combination with thermal effects. Both cryogenic fluids, i.e., liquid nitrogen and liq-uid hydrogen, and water were simulated at two cavitation regimes (sheet cavitation and unsteady cavitation) on two different geome-tries (a quarter caliber hydrofoil and an NACA 0015. A popula-tion balance equation model solved using the extended quadrature-based method of moments was implemented into a homogeneous mixture/mass transfer model in combination with an extended Schnerr-Sauer cavitation model.
