Henrik Alfredsson phal@mech.kth.se Affifliation: Linné FLOW Centre, KTH Mechanics, Stockholm, Sweden Topics: - Wall bounded flows Abstract: The present work builds upon the diagnostic plot for the streamwise turbulence intensity [Alfredsson & Örlü, 2010] and generalises it for higher-order (even and odd) moments providing a general description of the probability density distribution of streamwise velocity fluctuations. Turbulent boundary layers (up to a friction Reynolds number of 20'000) are employed and demonstrate its feasibility to scale data throughout the overlap and outer region. |
