Solar Collector Durability Evaluation by Stagnation Temperature Measurements

Journal of Solar Energy Engineering, 1983
An 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.

Electron temperature measurements along a stagnation point streamline

The Physics of Fluids, 1973
Experimental 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.

Stagnation temperature of a two-phase system

International Journal of Mechanical Sciences, 1971
Abstract A simple and accurate expression for the stagnation temperature of a two-phase system is developed in terms of the measurable properties of the free stream and tested with data from steam tables. Good agreement was found to exist.

Velocity and Temperature Profiles for Stagnation Film Cooling

Journal of Turbomachinery, 1991
Experiments 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 ...

A representation for the temperature field near the stagnation region in oblique stagnation flow

Physics of Fluids A: Fluid Dynamics, 1990
Oblique 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.

Effects of Wall to Stagnation Temperature Ratio on Hypersonic Corner Flows

35th AIAA Fluid Dynamics Conference and Exhibit, 2005
Numerical solutions of laminar, hypersonic, viscous, high temperature, perfect gas flows over compression corners are obtained. The effects of corner angle (θw) and wall to stagnation temperature ratio (Tw/T0) on flow variables, especially on surface pressure distributions and surface heat transfer rates are investigated.

Design Space Exploration of Stagnation Temperature Probes via Dimension Reduction

Volume 2C: Turbomachinery, 2020
Abstract The measurement of stagnation temperature is important for turbomachinery applications as it is used in the calculation of component efficiency and engine specific fuel consumption. This paper examines the use of polynomial variable projection to identify dimension reducing subspaces for stagnation temperature probes.

Laminar Stagnation-Point Heat Transfer for a Two-Temperature Argon Plasma

AIAA Journal, 1984
A theory for the heat transfer to the stagnation-point boundary layer of an axisymmetric blunt body in a subsonic two-temperature argon plasma flow was developed. Two-temperature transport properties were calculated from the rigorous kinetic theory and are employed in solving the multifluid problem formulated with a wall sheath boundary condition.

Stagnation temperature and molecular weight effects in jet interaction

AIAA Journal, 1969
The 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.

Stagnation point heat transfer from laminar, high temperature methane flames

International Journal of Heat and Fluid Flow, 1984
Abstract Combustion of methane-rich fuels frequently provides forced convective heating in industry, and the ability to predict the rate of heat transfer from such flames to solid surfaces is often desirable. Mathematical modelling of stagnation point heat flux has been achieved by numerical solution of the boundary layer equations, and by an ...
