Aeolian processes and effects

High Reynolds number turbulent boundary layer measurement is performed in the RTRI's Large-scale low-noise wind tunnel in Maibara Japan. The momentum thickness Reynolds number is up to approximately 7×104 . The mean velocity profile shows a clear log-law region with Kármán constant 0.38. The turbulent intensity profile also shows the log-law scaling predicted by attached eddy model. These data will be used as the fundamental data base made in Japan which is also applicable to industrial application including railway technology.
