Fluid flow and heat transfer in high-temperature porous matrices for transpiration cooling( Book )

1 edition published in 1966 in English and held by 1 WorldCat member library worldwide

A detailed study of fluid flow and heat transfer characteristics in porous matrices has been performed. Refined prediction methods for pressure and temperature distribution in porous matrices have been developed to include the effects of gas conduction, internal heat sources, chemical reaction, non-steady state flows and slip flow. The show system feasibility, a high-temperature multilayer matrix system has been developed. Six specimens, one inch in diameter, were fabricated and tested in an oxyacetylene flame with and without transpiration cooling. Some tests were performed under a cold wall heat flux of 235 Btu/ft sq-sec. It was found that the specimens can withstand a surface temperature of over 3600 F for a period of 30 minutes. Thus, it has been demonstrated that a transpiration cooled thermal protection system may be developed for space vehicle applications. (Author)
Investigation of fluid flow and heat transfer in porous matrices for transpiration cooling( Book )

1 edition published in 1966 in English and held by 1 WorldCat member library worldwide

An investigation was conducted to determine the heat transfer and fluid flow characteristics in porous matrices for transpiration cooling. Governing differential equations were derived and solved using realistic boundary conditions. Parameters governing the resulting temperature and pressure distributions in porous matrices were identified. Geometry, transient, and dissociation effects on temperature and pressure distributions were determined. Fluid flow and heat transfer characteristics in two-phase flows and multilayer matrices were also analyzed. Experimentally, 301 test runs were performed to measure the temperature distribution and pressure drops across the porous matrices using air, nitrogen, helium, and water as collants. Satisfactory agreement between calculated and measured temperature profiles was obtained. Information on permeability of porous matrices was derived. Good correlation was accomplished for viscous permeability as a function of porosity. (Author)
