【Abstract】

<正>Direct numerical simulation of a fully developed turbulent pipe flow up to 30R in length at Re_D = 35 000 was performed to investigate the spatial structures associated with large- and very largescale motions.Instantaneous fields showed that very long meandering motions exceeding 30R exist in the turbulent pipe flow and the streamwise length scale of the structures based on the two-
