应用３种湍流参数计算方法（移动时窗法、傅里叶反变换法、时间平均滤波方法）对倒拖工况下ＴＹ１１００发动机缸内湍流参数进行了计算．通过计算自相关系数、标准一维能谱密度、Ｔａｙｌｏｒ微分时间尺度，对３种数据处理方法进行了比较，并研究了平均“时窗”宽度、相关窗宽度对计算结果的影响．结果表明，３种方法得到的结论基本上是一致的，平均“时窗”宽度、相关窗宽度在一定范围内的变动对计算结果影响很小．
Three kinds of turbulence parameters calculation method (moving time window method, inverse Fourier transform and time average filtering method) were used to calculate the turbulent parameters in the TY1100 engine under the inverted condition. The three data processing methods are compared by calculating the autocorrelation coefficient, the standard one-dimensional spectral density and the Taylor differential time scale, and the influence of the average width of the “time window” and the width of the relevant window on the calculation result is studied. The results show that the conclusions obtained by the three methods are basically the same. The average “time window” width and the change of the relevant window width within a certain range have little effect on the calculation results.
