内容記述 | To estimate the nonlinear transient moment acting on spinning square cylinders in a plane normal to the flow direction, the force and moment coefficients were measured for a semi-finite square cylinder (fineness ratio 5) settled in a wind tunnel. Yaw angle β of the model was changed through a range of -45deg to 45deg and the Reynolds number was varied from 0.7×10(exp 5) to 5.7×10(exp 5). The results show : (1)Up to β(approximately)equal to 10deg the yawing moment coefficient Cn increases gradually and the magunitude is less than 1/3 of the two-dimensional square square cylinders. The Cn begins to increase rapidly from β(approximately)equal to 10deg showing the maximum value at β=16deg. (2)The effect of the Reynolds number on the forces and the moments is small compared to that for a circular cylinder. (3)The velocity compoment directing to the finite end of the semi-finite square cylinder is great in the separated region around the cylinder. | |||||
