Abstract

The present study makes an effort to find out the location of the drag, stream lines and contours of static pressure in the flow field passing through the square cylinder in incompressible viscous media. For this work, different values of Reynolds Numbers have been chosen. The distance of both the walls from the bluff body has been kept unaltered. It is observed that the vortices are attached with the rear side of the cylinder. With the increase in Reynolds Number the size of the vortices becomes smaller and the vortices start displaced from the rear side of the cylinder. At about Reynolds number 250, it is noticed that the vortices may not be attached with the rear side of the cylinder but pressure difference zones may be found to be formed in the top and bottom corner of the front side of the cylinder. It has also been observed that the same nature of stream lines may be found in front of the bluff body for different Reynolds Number which is varied after passing the bluff body. Besides, a cavity zone which was small in size for low Reynolds Number becomes larger with the increase in Reynolds number. All these observations have been made to see the issues related to the location and magnitude of Drag for the in compressible viscous flow passing through the square cylinder for the fixed wall distance with varying Reynolds Numbers.
