Abstract : The report presents heat transfer modeling of Thrust Vector control systems using the PHOENICS computer code. Simple two-dimensional wedged blunt bodies have been examined in supersonic cold flow, for both laminar and turbulent flow cases. The research presents a numerical solution of the supersonic compressible viscous two-dimensional flow field. Post calculations were done to estimate skin friction coefficient, surface heat flux, heat transfer coefficient and Stanton number distributions in both wedge and blunt cases.
