This paper presents the computational analysis of the effect of aero spikes on bluff bodies. In the present study, a blunt nosed model was designed with and without spike. Two different shaped spikes were chosen for our study. Efforts were taken to obtain the flow pattern and the pressure distribution field over the nose of the blunt body. Flow pattern was observed and recorded for different shaped spike attached in-front of the body. A comparative study was also done to observe which shape of the aero spike provides a better zone of the pressure field. It is observed that the radius of curvature of the streamline gets reduced by aero spike. Also, there occurs a deflection in the streamline which in turn resulted in creating a narrow zone of the positive pressure region. The zone of influence gets reduced by hemispherical shaped spike. The models were designed using CATIA V5 software and the analysis were carried out using ANSYS software packages.
