Periodic turbulent shear flows
Abstract
The results of Ramaprian and Tu (1982) on fully developed periodic turbulent water flows in pipes are summarized and compared with those obtained for time-mean zero-pressure-gradient periodic turbulent boundary layers in the periodic-flow water tunnel at the University of Iowa. The data are presented in graphs and characterized. At high frequency and amplitude, small but detectable time-mean-velocity effects with similar Stokes-layer thickness and near-wall phase angle about 10 deg are observed in both regimes.
