Research about the techniques of burst detection in turbulent boundary layer with the mu-level algorithm

In order to resolve the problems that the analysis results of mu-level algorithm were influenced easily by measurement and detection parameters, the adaptability of burst-detection in turbulent boundary layer were researched in detail. Through contrast analysis of vertical testing position, sampling frequency, sampling time, boundary-parameter and accessional determinant condition, the influence rules of above factor on burst-detection were acquired, and feasible approaches to enhance burst frequency veracity in turbulent boundary layer were discussed. Finally, a four-step method of detecting burst frequency with mu-level algorithm (fore-sampling, fore-analysis, sampling, detection analysis) was summarized.
