Abstract

The flow around an obstacle represents a challenge in fluid mechanics problems and practice. So, it is significant to investigate the hydraulic behaviour around the obstacle and the response of the obstacle which encounters the flow suddenly. The target of the present paper deal with the investigation numerically the effect of changing the vane angle on the hydraulic field around the cylinder and the response of the cylinder to the angle change. The vane has an angle shape with different angles ranging from 20 degrees to 90 degrees, the dimension of the angle is adopted as a function of the cylinder diameter. The study concentrates on the average flow velocity, strain rate, shear stress, static pressure, dynamic pressure, pressure coefficient, skin friction coefficient, drag coefficient, and lift coefficient. The obtained result shows a noticeable variation in the response of the hydraulic field around the cylinder especially in average flow velocity, static pressure, dynamic pressure, strain rate, and shear stress. The negative lift coefficient and negative drag coefficient appear in the numerical investigation. Also, a negative pressure coefficient is found.
