Drag reduction geometries is one of the burning issues in the present aerodynamics on which vast range of work is going on. Generally drag is the force exerted by the medium on the vehicles in the direction linear to the motion of the medium. Many of the researchers have developed some techniques like spike attachment to the front nose of the body, breathing blunt nosed body, splitter plate, fore body surface roughness, rounding the vertical corners of vehicles, making small holes to the model. The study of flow past the blunt nosed body with spikes having different overhead geometries like spike, double arrowed spike, semicircle, semicircle with arrow are studied. In this the flow past the blunt nosed body is studied experimentally. The flow parameter drag coefficient is calculated for different Reynolds number using drag co-efficient relations and results obtained are validated. The experimentation is carried in an open type channel. The present research involves calculation of drag co-efficient for blunt nosed body with different overhead geometries. The focus of the present research is on finding the drag coefficient both by experimentally and analytically.
