抄録

Turbulence structures have been studied in the fully-developed turbulent flow through a pipe with a square cross section using velocity measurement together with flow visualization. Ejection and sweep, observed in a wall turbulent flow, were confirmed in the wall region except for the vicinity of corners. The relation between these structures and velocity fluctuations was investigated in view of the profiles of probability density functions. As a result, it was shown that ejection and sweep contribute to the skewness factors of velocity fluctuations. In addition, valuable information about the conditional sampling of these structures was obtained.
