摘　　要：为了探究和验证气体动理学方法在处理高超声速飞行器的准确性、鲁棒性和计算效率,采用统一气体动理学格式和基于SU2开源平台开发的气体动理学无黏通量(KIF)格式(SU2-KIF),针对来流马赫数Ma=6~12、飞行高度H=30~70 km以及飞行迎角5°~20°下,HTV-2典型高超声速飞行器的定常绕流开展了数值模拟工作,并对飞行器表面热流、压力的分布情况,以及气动力、力矩系数进行统计,分析了飞行器在飞行过程中的气动力和气动热变化情况。To investigate and verify the accuracy,robustness,and computational efficiency of the gas kinetic method in dealing with hypersonic vehicles,numerical simulation is conducted by means of a unified gas kinetics scheme(UGKS)and a gas kinetics inviscid flux(KIF)scheme developed based on the Stanford University Unstructured(SU2)open-source platform(SU2-KIF).The simulation focuses on the steady flow around the HTV-2 typical hypersonic vehicle under the conditions of an incoming Mach number ranging from 6 to 12,a flight altitude ranging from 30 km to 70 km,and a flight angle of attack ranging from 5°to 20°.The distributions of heat flow and pressure on the vehicle surface,as well as the aerodynamic force and moment coefficients,are statistically analyzed,and the changes in the aerodynamic force and aerothermal effects during the flight process are investigated.
