The mixing layer behind a slanted trailing edge

  • Conference paper

Part of the book series: Fluid Mechanics and Its Applications ((FMIA,volume 24))

Abstract

The mixing layer behind a slanted trailing edge is investigated experimentally with hot-wire-anemometry and numerically using a discrete vortex method to simulate the flow. Mean values and velocity correlations show behavior similar to the plane mixing layer, but with a smaller spreading rate in the flow direction. The typical coherent structure is a vortex with its axis oriented along the mean vorticity direction. Proper Orthogonal Decomposition, cross correlations and pseudo visualization are used to identify eddy structures imbedded in the stochastic turbulent flow.
