Abstract:
For plane channel flows with a constant pressure gradient and for constant-pressure shear layer flows, a simple closure scheme for the Reynolds-averaged Navier–Stokes equations is proposed as an alternative to eddy-viscosity-based models. The closure scheme makes it possible to compute flows at any Reynolds number, including near the laminar-turbulent transition.
Key words:shear layer, two-dimensional Couette flow, laminar-turbulent transition, bifurcation model of turbulent flow.
