Incompressible flows around an inclined circular cylinder have been calculated by the finite difference method. The third-order upwind scheme is used to simulate high Reynolds number flow, and a no turbulence model is employed in this study. Computations are carried out at Reynolds number of 2000 and the yaw angle is changed from 0 to 60 degrees in order to observe its effect on the flow. Moreover, the effects of the boundary layer generated by the side wall are also investigated. The calculated pressure distributions around the cylinder are compared with experiment, and the agreement is satisfactory. The results of this computation show details of the flow especially in the wake region, and it is found that the yaw angle and the boundary layer on the side wall greatly affect the location of the separation point and, therefore, the wake structure.
