| Abstract: | A flow around a circular cylinder in a uniform shear flow at high Reynolds number is numerically investigated by the use of the discrete vortex- approximation. The drag coefficient, lift coefficient, Strouhal number, poaitions of separation point and vortex patterns are given by this calculation. They are reasonable and in Agreement with experimental results. |
