傾斜円柱まわりの流れの数値計算

抄録

Incompressible flows around a yawed circular cylinder at Reynolds number 2000 have been calculated by the finite difference method based on the third-order upwind scheme for approximating the nonlinear terms of Navier-Stokes equations. No turbulence model is employed in this study. Computations are carried out in cases with and without end plates in order to investigete the effect of them on the flow. The calcurated pressure distributions around the cylinder are compared with experimental data and the agreement is satisfactory. The results of this computation show the details of the flow especially in the wake region and it is found that the existence of the end plate greatly affect the location of the separation point.
