摘要
给出一种用分裂热膜测量二维非定常湍流流动的方法。提出了两种新的数据处理算法并说明了其在计算精度和其它方面优于现有的数据处理算法。这一方法被成功地应用于对一准二维扩压器内的复杂湍流分离流动的测量。结果表明分裂热膜是测量研究带回流的复杂湍流分离流动的有力工具。
A method of using split hot film is presented in the measurement of two dimensional Abstract A method of using split hot film is opresented in the measurement of two dimensinoal unsteady turbulence flows.Two noval data reduction algorithms were proposed and their merits and accuracies over existing algorithms were also presented.The method was successfully applied to the measurement of the complex turbulence separating flow in a quasi-two dimensional diffuser and it was shown that the split hot film is one of the powerful tools for the study ofcomplex turbulence flows with separation and reversal flow.
