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.

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.

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 ...
