Coupling Viscous Vorticity Equation (VISVE) method with OpenFOAM to predict turbulent flow around 2-D hydrofoils and cylinders

The VIScous Vorticity Equation (VISVE) method has already been applied to solve the laminar flow around a cylinder and a hydrofoil at low Reynolds numbers. This method is more computationally efficient and spatially compact than a viscous flow method based on primitive variables. However, the VISVE method fails at high Reynolds numbers due to the effects of turbulence. In this thesis, a synchronous coupling method was developed to couple the VISVE and a turbulence model in OpenFOAM, enabling the VISVE method to solve the turbulent flow at high Reynolds numbers in a 2-D hydrofoil case and a 2-D cylinder case. The velocity, vorticity, and pressure calculated by the coupling method agree well with the results obtained by a RANS method.Civil, Architectural, and Environmental Engineerin
