Reassessment of modeling turbulence via Reynolds averaging: A review of second-moment transport strategy

This paper examines the evolution of closing Reynolds-averaged Navier–Stokes equations by approximating Reynolds stresses via second-moment transport themselves. strategy first proposed Rotta is markedly in contrast to more usual approach computing an effective “turbulent viscosity” deduce turbulent as a Newtonian fluid laminar motion. covers main elements development this and shows examples applications complex shear flows that collectively include effects three-dimensional straining, force fields, time dependence affect flow ways cannot be readily mimicked with eddy viscosity model.
