Space-time correlations in turbulent flow: A review
@article{Wallace2015SpacetimeCI, title={Space-time correlations in turbulent flow: A review}, author={James M. Wallace}, journal={arXiv: Fluid Dynamics}, year={2015} }
This paper reviews some of the principal uses, over almost seven decades, of correlations, in both Eulerian and Lagrangian frames of reference, of properties of turbulent flows at variable spatial locations and variable time instants. Commonly called space--time correlations, they have been fundamental to theories and models of turbulence as well as for the analyses of experimental and direct numerical simulation turbulence data.
