Direct numerical simulation of jets in a cross turbulent boundarylayer flow

摘要

A numerical study has been performed to investigate theinteraction of jets in a cross turbulent boundary layer flow using thedirect numerical simulation technique. The bulk mean velocity of the jetis a half of the free-stream velocity. Turbulent vortex shedding isobserved behind jets and is believed due to three dimensional effects.The formation of a separation bubble in front of the injection hole andvortex interactions behind the hole are also observed
