Abstract
This paper deals with the computation of unsteady cavitating flow around a twodimensional
wedge by using Unsteady Reynolds Averaged Navier-Stokes (URANS)
flow solver. Because of accuracy deterioration problem due to excessive numerical
dissipations for low Mach number unsteady flow, properly scaled RoeM and
AUSMPW+ numerical flux schemes are used to accurately compute unsteady
cavitating flow. Fast Fourier Transform (FFT) analysis results of experiments and
computations are compared to show similar dominant frequencies of shedding vortices.
Shedding pattern and location of vortices are also compared to show similar behavior
of each flow result.
