This paper presents devices, measuring equipments, data processing and its major experimental results for turbulent boundary and boundary layer/ shock wave interaction in 2-D flate plate at Mach number 2.048. Cross-sectional area of wind tunnel test section is 0.6×0.6 m2, Reynolds number is 2.1×107 per metre and Reynolds number Res0 which .take boundary layer thickness of shock wave interaction region as reference length is approximately equal to 106.Experimental results of velocity profile u/u, for turbulent boundary layer in 2-D flate plate are approaching to(h/δ)1/7 , and relatively agree well with numerical results of finite difference solutions for 2-D compressed boundary layer equations. The qualitative distributed rules for dynamic eddy viscosity coefficient εm along flow lines which are derived from experimental results in boundary layer/shock wave interaction are also presented in this paper.

本文介绍了M=2.048的二元平板紊流附面层和附面层与激波(激波板相对气流为8.9°)干扰实验的设备、测试仪器、数据处理以及主要的实验结果。实验用的风洞试验段截面积为0.6×0.6米~2,每米长雷诺数月Re=2.1×10~7,以激波干扰区附面层厚度为参考长度的雷诺数Reδ_0)≈10~6。 二元平板紊流附面层速度型的实验结果接近于u/ue=(h/δ)~(1/7),而且与二元可压缩附面层方程有限差分解的数值结果符合较好。实验结果与二元平板不可压附面层壁面定律和尾迹定律公式计算值的变化规律接近,但计算结果偏大些,而与速度亏损定律的结论则是一致的。 文中亦给出了由实验结果推算的激波附面层干扰时动涡粘系数ε_m沿流线的定性分布规律:在附面层内层区域,ε_m通过干扰区是逐渐增大的,至干扰区下游时恢复到某一大干上游区的ε_m值。而在外层区域,ε_m在干扰区是先减小后再增大,这时下游区的ε_m略大于上游区的ε_m值。

In this paper, niche genetic algorithms are used to optimize the performance of a distributed 3 sensor OS CFAR detection system with different reference lengths and signal to noise ratios. A set of quasi optimum results is given and analyzed, which proves that niche genetic algorithms are efficient for this optimization. The influences of the nonidentity in environment on the performance of the distributed OS CFAR detector for different fusion rules are discussed subsequently. The results indicate that when OR fusion is employed, the system is robust to the nonidentical variety of detection environment, while 2 of 3 and AND fusion are sensitive in the same situation.
