Numerical simulations of turbulent plane channel flows
Abstract
The unsteady NavierStokes equations for incompressible fluids have been solved in order to simulate turbulent plane channel flow. The method involves a semiimplicit time scheme in which the pressure is calculated iteratively to satisfy a global instability condition. It is assumed that the flow is homogeneous in both the longitudinal and transverse directions. Although similar asymptotic flows are achieved by the imposition of a constant average pressure gradient and a constant fluid flow rate, the laminar Poiseuille flow is destabilized much more rapidly using the constant flow rate method.
