Analysis of Rarefaction Effects in the Hypersonic Rarefied Wind Tunnel
説明
A hypersonic rarefied wind tunnel (HRWT) has lately been developed at Japan Aerospace Exploration Agency. Flow characteristics of hypersonic rarefied flows have been investigated experimentally and numerically in this work. By conducting experiments of a pendulous sphere model and pitot tubes, we have probed flow characteristics in the test section. We have improved the understandings of the hypersonic rarefied flows by integrating a numerical approach with the HRWT measurement. Moreover, rarefaction effects on the impact pressure measurement have been analyzed by carrying out particle simulations, and good agreement was obtained between the measured and computed impact pressure. Finally, a method for the determination of surface accommodation parameters in HRWT has been proposed by utilizing a three degree-of-freedom measurement system with a plate model.
