Abstract

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.
