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.

Distortion compensation for generalized stereoscopic particle image velocimetry

TL;DR: In this article, a general experimental calibration procedure is described which determines the magnification matrix of a distorted imaging system, and an algorithm is presented to compute accurate velocity field displacements from measurements of distorted PIV images.

Two-dimensional convection from heated wires at low Reynolds numbers

TL;DR: In this article, the theoretical heat transfer relation based on the Oseen approximation is approached asymptotically as R → 0, provided free convection is negligible, which is the case when the Reynolds number is less than the cube root of the Grashof number.
