The characteristics of hypersonic rarefied flows have been investigated experimentally and numerically in this work. Using a sphere pendulous model, the test flow has been probed by measuring its displacement due to the aerodynamic force. In addition, a spatial variation of total pressure of the test flow has also been measured by using total pressure tubes. The flow field from a conical nozzle to a test section was simulated by computational fluid dynamics/direct simulation Monte Carlo loosely coupled computations, and the flow fields were deduced by integrating experimental and numerical results. Consequently, a 25-mm hypersonic rarefied core flow was obtained using a 45-degree conical nozzle with a Mach number greater than 10 and a Knudsen number greater than 0.1., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0062070036, レポート番号: JAXA-SP-13-001E}, pages = {407--415}, publisher = {宇宙航空研究開発機構(JAXA), Japan Aerospace Exploration Agency (JAXA)}, title = {Integration between Measurements and Particle Simulations for Hypersonic Rarefied Flows}, volume = {JAXA-SP-13-001E}, year = {2013} }
