摘要
基于超音速流动无约束化过程的分析，建立了洞壁自适应迭代调整方案以及最小干扰壁对比实验方案．进行了洞壁自适应技术的实验研究，首次在二维柔壁自适应凤洞中达到了国外三维自适应壁风洞消除洞壁干扰的效果。文中分析了二维柔壁风洞进行三维模型超音速实验的技术特点。探讨了提高其技术潜力的途径．
In 1990,a flexible wall nozzle was used by Wcdemeyer et al as a fairly satisfactory exploratory 2--Dadjustable test section with which they made the preliminary attempt to suppress wall interference for 3--Dmodel testing at low supersonic speed[6].Research performed by the authors at NPU is believed to be a big step beyond that of Ref.16].A highspeed 2-D flexible wall adaptive wind tunnc.l was designed, manufactured and put into running and it, inconjunction with improved testing technique, achieves wall in...
