Local correlation-based transition model for aerodynamic flows in wide speed range

open access: yesEngineering Applications of Computational Fluid Mechanics
A local correlation-based transition model is developed for aerodynamic flows in a wide speed range. New localized methods for the momentum-thickness Reynolds number are introduced for constructing local transition indicators. New transition correlations

Future Prospects for Hypersonic Flight Test For University Students [PDF]

open access: yes, 2005
The transport to space of satellites and experiments with conventional expandable rockets is a very expensive and time demanding business and therefore almost prohibitive for Universities and High-School or Colleges laboratories.

Transition mechanisms in hypersonic wind-tunnel nozzles: a methodological approach using global linear stability analysis

open access: yesFlow
Base-flow computations and stability analyses are performed for a hypersonic wind tunnel nozzle at a Mach number of 6. Isothermal and adiabatic wall boundary conditions are investigated, and moderate stagnation conditions are used to provide ...

Effect of wall temperature on separation bubble size in laminar hypersonic shock/boundary layer interaction flows

open access: yesAdvances in Mechanical Engineering, 2019
At hypersonic speeds, the external wall temperatures of an aerospace vehicle vary significantly. As a result, there is a considerable heat transfer variation between the boundary layer and the wall of the hypersonic vehicle.

Experimental study of slender vehicles at hypersonic speeds

open access: yes, 1996
An experimental investigation of the hypersonic flow over (i) a wing-body configuration, (ii) a hemi-spherically blunted cone-cylinder body and (iii) a one-half- power-law body has been conducted for M,, = 8.2 and Re,, = 9.35x104

Some hypersonic intake studies [PDF]

open access: yes, 2006
A 'two dimensional' air intake comprisipg a wedge followed by an isentropic compression has been tested in the Cranfield Gun Tunnel at Mach 8,2. These tests were performed to investigate qualitatively the intake flow starting process. The effects of cowl
