Overset Grid Method for Large Eddy Simulation of Turbulent Flows Around Bluff Bodies
Keyword(s):
The large eddy simulation of turbulent flow around a rectangular cylinder with side ratios of 1.0, 2.0, 2.67, and 3.0 at Re = 22000, is carried out using an overset grid system. In order to improve mass conservation along the boundary of computational domains, numerical procedures are proposed. The aerodynamic forces of rectangular cylinders can be predicted numerically. Details of pressure distributions along the side surface of the cylinder and turbulence structures in the wake is discussed, because there is a difference in accuracy of computational results in terms of the side ratio.
