Effect of plain shear velocity profile over a streamline cylinder

Abstract

Flow with plain shear velocity profile with high Reynolds Number (Re = 0.5 ×10 6 to 3.6×10 6 ) around a flat (2D) streamlined cylinder, is simulated by using a k-ε turbulence model. The main target of this study is to assess the influence of plain shear velocity and axis ratio on the important flow variables, such as drag force, point of separation and mean drag coefficient, along the exterior surface of a flat elliptical cylinder. Drag force over a circular cylinder as compare to elliptical cylinder is higher. Reduction in drag may be increased by reducing the axis ratio with plain Shear velocity profile. The point of separation moves forward as the cylinder became streamlined.
