Stagnation-Point Heat Transfer in a High-Temperature Inert Gas

The Physics of Fluids, 1962
Stagnation-point similarity solutions of the laminar boundary-layer equations are calculated for a thermally and calorically perfect gas with Prandtl number ⅔ and viscosity proportional to a power of the absolute temperature (μ ∝ T1−α). The parameter α is varied from 0 to 0.5, and the enthalpy ratio across the boundary layer from 0.01 to 0.80.

Fuel Stagnation Temperature Effects on Mixing with Supersonic Combustion Flows

Journal of Propulsion and Power, 1997
An 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,

Optical Determination of Stagnation Temperature Behind a Gas Sampling Orifice

Journal of Heat Transfer, 1990
A technique has been developed for measuring the temperature during a transient combustion event. It combines the features of atomic resonance absorption and direct sampling to produce a relatively simple, intrusive diagnostic technique to obtain time-resolved measurements.

Measurements of Stagnation-Point Temperature with High-g Telemetry

IEEE Transactions on Aerospace and Electronic Systems, 1968
Measurement of phenomena associated with free-flight models in ballistic ranges has been made possible with the development of a stable on-board miniaturized telemetry system that will withstand large gun-launch accelerations. The results of body temperature measurements behind the stagnation point with thin-film temperature gauges are presented and ...

Simulation of Solar Water Collector Stagnation Temperature

This publication introduces the simulation procedure of solar water collector stagnation temperature. The calculations are for central solar water heating systems in multi-apartment residential buildings in Tel Aviv. The stagnation may be caused by the system's circulation pump being shut down by incorrect pump control.

Determination of Real-Gas Stagnation Temperature Based on Mass-Flow Consideration

Journal of the Aerospace Sciences, 1961
ONE OF THE MAJOR PROBLEMS encountered in the operation of high-enthalpy test facilities is the determination of high stagnation temperatures (T > 4,000°R). Since these temperatures normally exceed the capabilities of available thermocouples, it is often necessary to resort to one of the various optical methods—such as pyrometry or the sodium-line ...
