Abstract
Purpose
The purpose of this paper is to predict the unstable cavitation shedding flow around a 2D Clark-y hydrofoil.
Design/methodology/approach
The paper studies Partially Averaged Navier-Stokes (PANS) model which was employed in the two-phase flow with a homogeneous cavitation model.
Findings
Maximum density ratio affects the mass transfer rate between the liquid and the vapor significantly. The cavitating flow predicted by PANS model can resolve more turbulent scales by decreasing the parameter fk.
Originality/value
The accuracy of numerical prediction is improved by increasing the maximum density ratio and decreasing fk.
