Abstract

Understanding the fundamental properties of turbulence in high speed flows has been seriously limited by the lack of experimental techniques capable of generating instantaneous multipoint data. Previous measurements have relied largely on hot-wire probes, laser Doppler velocimetry, and schlieren to infer properties of turbulent structures. Such fundamental questions as the velocity at which these structures move, the scale of the structures, their form, and the corresponding vorticity fields are unresolved.
