Journal ArticleDOI
Vortex organization in the outer region of the turbulent boundary layer
TL;DR: In this paper, the structure of energy-containing turbulence in the outer region of a zero-pressure-gradient boundary layer has been studied using particle image velocimetry (PIV) to measure the instantaneous velocity fields in a streamwise-wall-normal plane.
Journal ArticleDOI
Spanwise structure and scale growth in turbulent boundary layers
TL;DR: In this article, the authors investigated spanwise structure and growth mechanisms in a turbulent boundary layer and found that the dominant motions of the flow are large-scale regions of momentum deficit elongated in the streamwise direction.
Journal ArticleDOI
An experimental investigation of mixing mechanisms in shock-accelerated flow
TL;DR: In this article, the mixing rate of a shock-accelerated cylinder of heavy gas in air is estimated experimentally for the first time in this type of flow and used to identify the regions of most intense post-shock mixing and examine the underlying mechanisms.
Journal ArticleDOI
Energetic spanwise modes in the logarithmic layer of a turbulent boundary layer
TL;DR: In this article, the power spectra of the streamwise component are measured in streamwise-spanwise planes throughout the logarithmic region of smooth flat-plate turbulent boundary layers at decreases with increasing distance from the wall, suggesting that the most streaky structures remain buried near the wall.
Journal ArticleDOI
Simultaneous particle-image velocimetry–planar laser-induced fluorescence measurements of Richtmyer–Meshkov instability growth in a gas curtain with and without reshock
TL;DR: In this article, the structure of the concentration and velocity fields in a light-heavy-light fluid layer subjected to an impulsive acceleration by a shock wave (Richtmyer-Meshkov instability) was studied using simultaneous particle-image velocimetry and planar laser-induced fluorescence (PLIF) measurements.
