Measurement Of Thermal Accommodation Coefficients Of Steel Surfaces, Wing On Ho Jan 1970

Measurement Of Thermal Accommodation Coefficients Of Steel Surfaces, Wing On Ho

Masters Theses

"The thermal accommodation coefficient plays an important role in low density thermal energy transfer measurement. The object of this investigation was to measure the thermal energy transfer between a heated test surface and a water cooled reference surface (flat black lacquer) consisting of two infinite concentric cylinders separated by dry air. Two machined and sanded steel cylinders with mean surface roughnesses of 25 microinches and 7.5 microinches were used as the test surfaces . Measurements were made in the pressure range of 1.2 x 10⁻⁶ mm Hg. to 1.8 x 10⁻⁶ mm Hg. and temperature range ...
