SURVEY OF LITERATURE ON CONVECTIVE HEAT TRANSFER COEFFICIENTS AND RECOVERY FACTORS FOR HIGH ATMOSPHERE THERMOMETRY

摘要

This report concerns heat transfer phenomena of rarefied gas flows, and is based on a lliterature survey of analytical and experi¬mental rarefied gas dynamics. Subsonic flows are especially empha¬sized for the purposes of meteorological thermometry in the high atmosphere Part one of the report deals with the heat transfer coefficients (in external subsonic rarefied flow) for three basic geometries — a flat plate, cylinder and sphere — in all flow regimes;i.e., free molecule flow (Kn > 10), transition flow (10 > Kn > 0.1), slip flow (temperature jump) (0.1 > Kn > 0.01), and continuum flow (En > 0.01).nIn port two, recovery factor for each geometry in subsonic rarefied flows is discussed. Uncertainties resulting from analyses of experimental data available at the present time are also presented.
