Near-Wall Similarity in a Shear-Driven Three-Dimensional Turbulent Boundary Layer

Abstract

Ten of eleven proposed three-dimensional similarity models identified in the literature are evaluated with direct wall shear, velocity field, and pressure gradient data from a three-dimensional shear-driven boundary layer flow. Results define an upper limit on velocity vector skewing for each model’s predictive ability. When combined with earlier results for pressure-driven flows, each model’s predictive ability with and without pressure gradients is summarized.
