运动平板附近圆柱绕流的数值模拟
Numerical Simulation of Flow Past a Circular Cylinder near a Moving Plane
摘要
Abstract
The flow past a circular cylinder near a moving plane was simulated. The circular cylinder was placed over a moving plane which moved at the same velocity of uniform flow at the inlet. The Reynolds number was 1 000 in present simulation. The gap ratio was defined as G/D, where G represents the nearest distance of circular cylinder to the moving plane and D is the diameter of the circular cylinder. Numerical simulations show that the flow patterns are very different at various gap ratios. Compared with those of flow past an isolated circular cylinder, the present lift and drag coefficients increase obviously, and the vortex shedding is suppressed by the plane.关键词
