Velocity and Temperature Profiles for Stagnation Film Cooling
Journal of Turbomachinery, 1991Experiments were conducted for film cooling through rows of slanted holes into the stagnation region of a two-dimensional blunt body with a circular leading edge. The rows were located at ± 15 deg +44 deg from stagnation. The holes in each row were spaced four hole diameters apart and were angled 30 deg to the surface in the spanwise direction ...

Stagnation temperature and molecular weight effects in jet interaction
AIAA Journal, 1969The purpose of this study was to investigate the effect of injectant stagnation temperature and molecular weight variation on the flowfield generated from secondary injection of a gas normal to a supersonic stream. Experiments were conducted at a primary stream Mach number of 2.80 in the Naval Postgraduate School supersonic wind tunnel.

Solar Collector Durability Evaluation by Stagnation Temperature Measurements
Journal of Solar Energy Engineering, 1983An analytical and experimental investigation was undertaken to evaluate an alternative method for measuring the thermal degradation of materials used in flat-plate collectors. This test method is based on measuring the temperature of the absorber under a no-flow condition before and after prolonged exposure.

A representation for the temperature field near the stagnation region in oblique stagnation flow
Physics of Fluids A: Fluid Dynamics, 1990Oblique stagnation flow has been the subject of previous work. In this Brief Communication, attention is restricted to the case in which the flow is steady, inviscid, and two dimensional. A general solution to the thermal field valid in the region of the stagnation point, which formally exhibits x dependence, is sought.

Electron temperature measurements along a stagnation point streamline
The Physics of Fluids, 1973Experimental observations of the electron temperature profile along a stagnation point streamline have been found to be in good agreement with the theory developed for the case where the interaction between an electron thermal layer and a viscous shock layer was considered.

Development of a stagnation temperature probe for supersonic combustion flows
High Temperatures-High Pressures, 1995As part of the French hypersonic programme (PREPHA), a probe has been developed to measure the stagnation temperature in an air/hydrogen supersonic combustion ramjet engine (SCRAMJET)

Simultaneous Measurements of Temperature and CO Concentration in Stagnation Stabilized Flames [PDF]
Flow, Turbulence and Combustion, 2012 An impinging jet burner was developed to investigate flame-wall interactions (FWI) using laser based diagnostics. CO concentrations were measured with two-photon laser-induced fluorescence (LIF) in combination with coherent anti-Stokes Raman spectroscopy (CARS) gas phase temperature measurements. Besides being the principal factor in chemical kinetics,

Fuel Stagnation Temperature Effects on Mixing with Supersonic Combustion Flows
Journal of Propulsion and Power, 1997An experimental study of the effect of fuel stagnation temperature on mixing in a supersonic hydrogen-air flame is described, The combustor consisted of a constant-area rectangular duct with a centrally located fuel-injection strut that spanned the width. A high-enthalpy stream of air was supplied by a free-piston shock tunnel, and heated hydrogen fuel,

Temperature-dependent heat sources or sinks in a stagnation point flow
Applied Scientific Research, 1961An analytical study has been made to determine the heat transfer characteristics of a stagnation point flow in which there are temperature-dependent heat sources or sinks. Results have been obtained for both strong and weak sources or sinks for a Prandtl number of 0.7.
