Wave drag is a significant parameter to be considered in designing high speed vehicles. It is well known that drag can be alleviated by modifying the flow field in front of the fuselage body. There are several techniques to the flow field ahead of a supersonic and hypersonic speed vehicles and the use of spikes are appears to be simplest and at an efficient means of reducing drag on the vehicle by bringing to control the flow separation at fuselage front face of wing body these devices called spikes, shocks will be shifting from fuselage front to spikes front. The present work involves study of subsonic transonic and supersonic speed flow over the fuselage model. Spikes have been considered for the purpose of drag reduction studies. The numerical results have been validated with literature data.
