Micro-cavity arrays have been identified as a potential passive device to disrupt and capture sweep events, which are responsible for the Reynolds stresses in the boundary layer. The application of micro-cavity arrays for drag reduction was proposed

The turbulence intensities and shear stresses in a turbulent boundary layer (TBL) are primarily associated with the presence of coherent structures, such as sweep and ejection events. Recent experiments using a passive method of controlling the TBL u

Coherent structures in a turbulent boundary layer have been shown to have an influence on the skin-friction drag acting on surfaces beneath the boundary layer. The use of micro-cavities on a flat surface has recently shown the potential to passively

In the present study, the optimal two-dimensional (2D) tripping technique for inducing a naturally fully developed turbulent boundary layer in wind tunnels has been investigated. Various tripping techniques were tested, including wires of different d

In the present study, the turbulent energy production within a fully developed turbulent boundary layer has been reduced using a variety of flushed-surface cavity arrays with different geometries embedded within a flat plate. The cavity arrays manipu

Cavity arrays have been identified as a potential passive device to disrupt and capture sweep events, which are responsible for the excess Reynolds stresses in the boundary layer. In the present study, the mechanism of the attenuation of captured swe

Cavity arrays have been previously identified to disrupt the sweep events and consequently the bursting cycle in the boundary layer by capturing the structures responsible for the Reynolds stresses. In the present study, the sensitivity of a flushed-
