Modelling of Hypersonic Flows and their Applications

Pradyumna Surwase*

This paper presents a detailed overview about the modelling of hypersonic flows and their applications like scramjets and detonation phenomenon. The computational analysis of a wedge as well as blunt shaped 2D re-entry vehicle was carried out in order to compare the drag. Also, the aerodynamic properties were studied for re-entry vehicle at different mach numbers. Various turbulence models were used to compare the hypersonic simulations. In the application part, NASA Hyper X-43A scramjet geometry was used a s a reference geometry and the throat areas of the combustion chamber section were used by 1.4 and 2.8 times respectively in order to improve the thrust and specific impulse. Two spike shaped struts were used as fuel injectors and simulations were carried out at different mach numbers. Simulations were also carried out for the outer section of NASA Hyper X-43A scramjet vehicle. For the detonation phenomenon, a single wedge shaped fuel injector was used for checking the stability of detonation waves and comparing it with deflagration.
