On the relationship between net-momentum fluxes and wall-normal velocity fluctuations

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Turbulent coherent events in wall-bounded shear flows have been shown to play a decisive role in the transport of sediment and other contaminants. The present work makes use of low-order cumulant expansions to show the particular relation between local, net momentum fluxes and the asymmetry in wall-normal and streamwise velocity fluctuations. A direct link is hence provided between these fluxes and the dominant contributions to the turbulent transport of momentum resulting from the bursting phenomenon.
