Abstract
Re-entry vehicles returning from space are exposed to very high velocities in atmosphere. The air friction along can cause very high temperatures to be developed at the vehicle wall. So the geometrical of the vehicle is of prime interest in designing the vehicle. The experiment on this project concentrates on understanding the various characteristics of hypersonic flow and re-entry vehicle and the reliability on CFD software for determining the flow characteristics. The analysis compares the flow characteristics using a wedge based and blunt nose based models. The capsule is modelled using Design Modeller and meshed in Ansys. The analysis is carried out using CFX. K-omega 2 equation SST model is used for turbulent modelling in CFX analysis. K-epsilon model is also used for comparing the results. Profiles of pressure, temperature and density are mainly studied.
