Investigation on aerodynamic characteristics of hypersonic rarefied gas flows has been essential for a variety of situations, such as the Super Low Altitude Test Satellite, earth reentries, or planetary atmospheric entries. At Japan Aerospace Exploration Agency, a 100-mm Hypersonic Rarefied Wind Tunnel(HRWT) has been developed. A 45-degree conical nozzle has been designed in this research, and rarefied hypersonic flows have been successfully generated with a Mach number greater than 10.In addition, an integration system between HRWT measurements and particle simulations has been developed, and this system enables us to improve aerodynamic prediction in hypersonic rarefied flows due to the determination of surface accommodation coefficients.

高超声速稀薄气体流的气动特性研究对于超低空试验卫星、地球再入、行星大气层等各种情况都是必不可少的。日本宇宙航空研究开发机构已经开发了一个100毫米高超声速稀薄风洞。设计了一个45 °锥形喷管，成功地模拟了马赫数大于10的高超声速稀薄流场。此外，建立了一个HRWT测量与粒子模拟的集成系统，该系统通过确定表面适应系数，改善了高超声速稀薄流场的气动预测。
