Theory of cross-correlation analysis of PIV images : Image analysis as measuring technique in flows

R. D. Keane, +1 more
TL;DR: In this article, cross-correlation methods of interrogation of successive single-exposure frames can be used to measure the separation of pairs of particle images between successive frames, which can be optimized in terms of spatial resolution, detection rate, accuracy and reliability.

Statistical properties of turbulence: An overview

TL;DR: In this article, the authors present an introductory overview of several challenging problems in the statistical characterization of turbulence and provide examples from fluid turbulence in three and two dimensions, from the turbulent advection of passive scalars, turbulence in the one-dimensional Burgers equation, and fluid turbulent in the presence of polymer additives.

Review vorticity considerations and planar shear layers

TL;DR: In this paper, Vorticity considerations were employed to experimentally analyze two plane shear layers: (i) a small Reynolds number two-stream layer (θΔU/ν = 4.8 × 103) and (ii) a high Reynolds number single-stream shear layer (U0θ/ν= 78 × 103).
