Keywords: Incompressible turbulent boundary layers Turbulent inflow Compact finite differences Staggered grid High-resolution a b s t r a c t A new high-resolution code for the direct simulation of incompressible boundary layers over a flat plate is described. It can accommodate a wide range of pressure gradients, and general time-dependent boundary(More)
Near-wall turbulence in the buffer region is qualitatively characterized in terms of recently-found nonlinear three-dimensional solutions to the incompressible Navier–Stokes equation for wall-bounded shear flows. Jiménez & Simens' (2001) traveling-wave solution for an autonomous wall flow, Nagata's (1990) steady and Kawahara & Kida's (2001) periodic(More)
This report describes the results of a relatively large-scale direct simulation of a turbulent boundary layer using a new simulation code, with emphasis on the extent of the contamination of the flowfield due to the inflow boundary conditions. The assumption is that the goal of the simulation is to explore the physics of the flow, about which it is(More)
