✦ Synopsis

A method is proposed for measurement of turbulence quantities of fluid flow. The motion of a swarm of small tracer particles supplied to turbulent flow is continually followed by high-speed tine-photography, from which velocity correlations and energy spectra are evaluated. It is applicable to the heterogeneous fluid flow as well as to the homogeneous fluid flow, and the Eulerian and Lagrangian correlations are determinate simultaneously. Validity of the method is confirmed by the comparison of some turbulence quantities in the present study with those obtained otherwise.
