Applications of Algebraic Reynolds Stress Turbulence Models Part 1: Incompressible Flat Plate

Abstract

The ability of the three-dimensional Navier – Stokes method, PAB3D, to simulate the effect of Reynolds number variation by using nonlinear explicit algebraic Reynolds stress turbulence modeling was assessed. Subsonic  at-plate boundary-layer  ow parameters such as law-of-the-wall velocity distributions, local and average skin friction, skin friction correlation, and shape factors were compared with direct numerical simulation calculations and classical theory at local Reynolds numbers up to 180 3 10. Each model displayed slightly different low and high Reynolds number characteristics, but generally compared very well with classical theories and data. No deŽ nitive advantage of one explicit algebraic Reynolds stress model over another was observed.
