Turbulence: Space-time statistical properties and behavior in supersonic flows
Abstract
Following a scientific cooperation beginning in 1954 with L. S. G. Kovasznay, and in his memory, in this paper is presented a survey of two of the main areas of research to which he contributed: (1) turbulence properties deduced through statistical conditional sampling and space-time measurements of correlations and contingencies; these include celerities, optimum correlations, memories, and coherent structures; and (2) the study of turbulence in supersonic flows initiated by Kovasznay; this include the use of mass-weighted averages, decrease of turbulence in expansion, increase in compression, strong Reynolds analogy extension, and temperature-velocity correlation conservation.
