Abstract
New anisotropic algebraic constitutive relations for the Reynolds stress tensor are formulated. These relations make it possible to model correctly three-dimensional turbulent flows which cannot be described on the basis of traditional modern semi-empirical models of turbulence. Along with the well-known nonlinear Saffman term, these relations contain new nonlinear terms which take the wall effect into account. Several two- and three-dimensional turbulent flows are calculated nu\-merically using the averaged Navier-Stokes equations. The calculation results are compared with known experimental data.
