STAGNATION POINT INJECTION IN HYPERSONIC FLOW
Abstract
The overall objective of this collaborative AFOSR proposal is to investigate the complex interactions between a hypersonic free stream and a jet oriented into the free stream, as well as the effects of this stagnation point injection on the boundary layer far downstream of the stagnation point on a slender body. Stagnation point injection (SPI) has the potential to create several desirable effects for hypersonic vehicles of interest to the US Air Force, including drag and heat flux reduction, in addition to altering the stability characteristics of the boundary layer far downstream of the stagnation point. However, the interaction between the free stream and the jet, known as the aerodynamic interference (AI), is characterized by significant amounts of unsteadiness and turbulence, which are challenging to model. The project will support two full-time PhD students, one each at Purdue University and Case Western Reserve University (CWRU).
