Abstract
A numerical model to study the time development of a two-dimensional turbulent flow around cylinders and the associated forces has been developed. The model is based on the discrete vortex method. The development of the turbulent boundary layer around the cylinders is included in this investigation. The boundary layer calculation is based on von Karman`s momentum equation, where the shape of the velocity profile in the boundary layer is assumed to be logarithmic. Only two-dimensional flow is considered. The vorticity equations are solved in a curve linear coordinate system. The curve linear coordinate system is generated from the Laplace equation. The coordinate lines are the streamlines and potential lines. The equations allow solution for a configuration of several cylinders. (au) (11 refs.).
