The relationship between the vortical structure and the wall shear stress in a blind trough cavity subject to a jet impingement

Original language description

In a blind trough cavity subject to a jet impingement, the jet switching phenomenon has been known for decades. The large vortices, formed by the Kelvin- Helmholtz instability play a crucial role in this phenomenon- they are the main cause of the fluid entrainment phenomenon, which consequently evoke the Coanda effect and finally results in the jet switch. As the jet swings, the vortical structure inside the cavity changes together with the impinigement point. The aim of this article is to describe therelationship between the wall shear stress, i.e. the motion of the impingement point, and the vortical structure.The analysed data were obtained using the TR PIV system, various cavity aspect ratios, Reynolds numbers and the impingement angles.
