Near-wall turbulence

Abstract

Topics presented include the similarity of organized structures in turbulent shear flows, a conceptual model of the viscous wall region, the effects of surface curvature on the law of the wall, and the role of inflectional velocity profiles in wall bounded flows. Also presented are a review of knowledge on pressure fluctuations, stochastic estimation of coherent structures in turbulent boundary layers, the effect of Reynolds number on the organized motion in a turbulent boundary layer, and the structure of turbulence in heat transfer. Also discussed are the effects of high free-stream turbulence on heat transfer in turbulent boundary layer, wave interaction and stability problems, the modeling of unsteady boundary layers, and the transport of enstrophy in a turbulent boundary layer.
