Journal ArticleDOI
Improved test time evaluation in an expansion tube
Christopher M. James,Timothy G. Cullen,Han Wei,Han Wei,Steven Lewis,Sangdi Gu,Richard G. Morgan,Timothy J. McIntyre +7 more
TL;DR: In this article, the authors proposed two new methods which can be performed using a high-speed camera and a simple circular cylinder test model to evaluate the effective test time of expansion tube expansion.
Journal ArticleDOI
Shock-tunnel investigations on the evolution and morphology of shock-induced large separation bubbles
R. Sriram,Gopalan Jagadeesh +1 more
TL;DR: In this paper, the strong interaction between an impinging shock wave and boundary layer on a flat plate, accompanied by a large separation bubble with a length comparable to the distance of the location of shock impingement from the leading edge of the plate, is studied.
Journal ArticleDOI
Effect of the axial cavity with an opposing high-pressure jet combination in a Mach 6 flow condition
TL;DR: In this article, the authors investigated the heat transfer variations and nature of shock around a blunt body with a cylindrical and parabolic cavity geometries combined with an opposing jet.
Journal ArticleDOI
A Numerical Study on High-Temperature Effects of Exploding Shock Waves
TL;DR: In this paper , a planar shock of initial strength MS = 3.0 was focused to a tiny region in space using a spherically converging test section, and it was found that the gas temperature inside the mushroom structure is higher than that across the reflected shock itself.

Experimental Investigation of Film Cooling Technique over a Blunt Body in Hypersonic Flow
TL;DR: In this article, the authors inject new coolants, i.e., mist (atomized water particles) and N2-CO2 mixture, and study the heat transfer variation over the surface of a blunt body in hypersonic flow.

Describing the Uncertainties in Experimental Results
TL;DR: The material presented in this paper covers the method of describing the uncertainties in an engineering experiment and the necessary background material, as well as a technique for numerically executing uncertainty analyses when computerized data interpretation is involved.

The flow of a jet from a body opposing a supersonic free stream
TL;DR: In this paper, a series of experiments is described in which a jet issues from an orifice at the nose of a body in supersonic flow to oppose the mainstream, and an analytical model of the flow is developed which suggests that the aerodynamic features of a steady flow depend primarily on a jet flow-force coefficient, and the Mach number of the jet in its exit plane.

An experimental investigation of the effect of ejecting a coolant gas at the nose of a bluff body
TL;DR: In this article, an experimental investigation has been made of the effect of ejecting nitrogen and helium coolant gases at the nose of a blunt body in the GALCIT 5 inch x 5 inch hype r sonic wind tunnel at a nominal Mach number of 5.8.
