Abstract
A re-entry capsule is the portion of a spacecraft which returns to earth following a space flight. In present paper, a fluent analysis is performed on two distinctive models of capsule and temperature contours are outlined. Firstly, the aft end formed in a sharp (slender body) shape forms a shock wave that touches the capsule and high temperatures are formed on the body, Whereas, the aft end is formed in a rounded (blunt body) shape, as this forms a shock wave that doesn't touch the capsule, and the heat is diverged away rather than melting the vehicle body and low temperatures are seen on the body. The capsule model was created in Solid Works, meshing and general post processing was carried out in Ansys fluent 14.0
