Abstract
Study on flow over skewed steps constitutes a vital branch of fluid mechanics. In the present study, the size of the wake zone behind the skewed steps and aerospikes of different shapes are visualized. Physics behind the wake zone with and without aerospike attached to the blunt-shaped object is investigated for different velocities ranges from 5 to 20 cm/s. Pressure uphill, zone of influence, flow separation and reattachment points are also observed for various skewed steps. Experimental analysis is carried out by using water channel setup which is manufactured to the designed dimensions. Work is further extended to determine drag force and coefficient of drag for skewed steps. Plots drawn with the velocities and zone of influence are analyzed with respect to different flow features. From the plots, it is clearly observed that the vortex formation is less for an object attached with a hemispherical spike.
