Receptivity of High-Speed Flows over Blunt Noses using Spectral Methods, Ph.D. Dissertation Sharif University of Technology ; Hejranfar, Kazem (Supervisor) ; Esfahanian, Vahid (Co-Advisor)
Abstract
The receptivity, transition and stability mechanisms of supersonic and hypersonic boundary layers to freestream disturbances are one of the most complex studies in fluid mechanics. It is well known that turbulent flows generate much higher shear forces on the surface of vehicles and hence much higher viscous heating rates than a laminar flow would at the same flight conditions. Therefore, the accurate prediction of boundary layer behavior is a critical part of the aerodynamic design of high-speed vehicles and thermal protection systems. Formation of a bow shock in front of the vehicle makes the receptivity of flow-field more complex than and different from those of low-speed subsonics. Since...
