Stagnation flow with a temperature-dependent viscosity

Journal of Fluid Mechanics, 1983
In this paper we derive solutions for two stagnation flows of an incompressible Newtonian fluid with infinite Prandtl number and exponentially temperature-dependent viscosity. The two stagnation flows are the impingement of a hot fluid against a cold wall and against a cold half-space of the same material.

Emittance from stagnation temperature study

Solar Energy, 1984
Variation of stagnation temperature of various coatings kept in an insulated one glass cover box is theoreticall analysed. This shows that it is possible to make an approximate estimate of thermal emittance of the coating of known absorptance from the knowledge of stagnation temperature, ambient temperature and solar insolation.

Radiation limitation of stagnation temperature in high temperature selective absorbers

Solar Energy, 1992
Abstract A sharp-cutoff wavelength high temperature selective surface has been modelled, with a view to determining the stagnation temperature as well as the likely operating temperature. It has been found that, under conditions of low optical concentration, a solar collector receiver coated in a sharp-cutoff surface may be able to operate with ...

Stagnation and Bulk Mean Temperature

2021
Earlier we have described various methods of temperature measurement. We have also discussed the measurement of temperature of a moving fluid, essentially at low velocities. However, when flow velocities of a gas are high (as, for example, in high subsonic or supersonic flows) the temperature of the gas under stagnation conditions is higher than the ...

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.

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.

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.

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 ...

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.
