VIScous Vorticity Equation (VISVE) for Turbulent 2-D Flows with Variable Density and Viscosity

Abstract

The general vorticity equation for turbulent compressible 2-D flows with variable viscosity is derived, based on the Reynolds-Averaged Navier-Stokes (RANS) equations, and simplified versions of it are presented in the case of turbulent or cavitating flows around 2-D hydrofoils.
