Direct numerical simulation of flow separation behind a swept, rearward-facing step at Re sub(H) identical with 3000

A 3D extension of a well-known 2D flow was investigated. The goal of study is to identify the influence of sweep on the separated flow behind the step edge. A series of direct numerical simulations were carried out. The transition process depends on the way how disturbances enter the laminar shear l...

Description
Summary:A 3D extension of a well-known 2D flow was investigated. The goal of study is to identify the influence of sweep on the separated flow behind the step edge. A series of direct numerical simulations were carried out. The transition process depends on the way how disturbances enter the laminar shear layer and the size of the separated flow region is found to be very sensitive with respect to magnitude and frequency content of background disturbances superimposed to the flow.
