The present chapter deals with heat transfer analysis around unspiked and spiked bodies at high speeds. A spike attached to a bluntnosed body drastically alters its flowfield and influences the aerodynamic heating in a high speed flow. The effect of spike length, shape and spikenose configuration is numerically studied at zero angle of by: 1.
