摘　　要：采用计算流体力学方法对用于激光辐照热效应实验研究的高亚声速流场模拟装置的近壁流场进行了数值计算,分别针对靶材固壁为平面和弧面的情况比较了实验区无侧板和有侧板时的流场品质,结果表明侧板与靶材固壁构成的半开放槽道能够形成更大范围的均匀流实验区。根据数值计算优化的实验区结构参数研制了流场模拟装置,流场校测结果与数值计算符合良好,流场品质能够满足激光辐照热效应实验研究的要求。The near wall flow field of a high-subsonic flow simulation facility, which is effect research of laser irradiation experiment, was calculated using CFD, and comparison of planar and arc wall of the target material with and without side plate shows that a semi-open used in thermal flow quality for channel formedby side plates and the target material wall will give a broader uniform flow area in the test section. The flow measurements of the simulation facility, which was built up according to the optimized parameters based on CFD, yield good agreement with numerical results, and the flow quality can meet the requirements of laser irradiation thermal effect experiments.
