Abstract

Summary: A hierarchical structure (HS) analysis (\(\beta\)-test and \(\gamma\)-test) is applied to a fully developed turbulent pipe flow. Velocity signals are measured at two cross-sections in the pipe and at a series of radial locations from the pipe wall. Particular attention is paid to the variation of turbulent statistics at wall units \(10
