ON THE BURST DETECTION TECHNIQUES IN WALL-TURBULENCE

Sun Kuihua; Shu Wei(Dept.of Mechanics, Tianjin University, Tianjif 300072, China)  
A comparision of the effectiveness and sensitivity of the mu-level, VITA,WAG,(uv)_2 burst-detection algorithms has been done. Measurements were made in a waterchannel using hot-film X-probes located in the near-wall region of a flat plate. Same setof data are used in the study with conditional sampling and conditional averages. Theapproach of acquiring the unique average bursting period are discussed.
