Abstract
A Reynolds stress model with a modification to the ε equation is shown to reproduce the essential new features observed by Moin et al. [Phys. Fluids A 2, 1846 (1990)] in three-dimensional turbulent channel flow. Perhaps the most significant of these features is an initial drop of turbulent kinetic energy; previous turbulence models do not predict this. The effect of the three-dimensional modification on the infinite swept-wing boundary layer is assessed. It is not large and is primarily restricted to a region near to the surface. A three-dimensional homogeneous shear flow is formulated and turbulence statistics are computed by solving a simple Reynolds stress model.
