✦ Synopsis

A study is made of the relative motion of particles to fluid in a turbulent dispersion. An equation is derived to describe the motion of particles. Motions of both fluid and particles are recorded continually by motion picture method, followed by Fourier-analyses. Even neutral-buoyant particles are found to be able to respond to the motion of turbulent eddies of fluid larger in linear scale than the order of their diameters. When density difference is not admissible, some reduction in the turbulence component velocity appears apparently, as expected in the derivation of the basic equation.

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 h

An attempt is made to make clear the correlation of particle-liquid hydrodynamics and mass-transfer mechanism in a turbulent dispersion where particles are freely-suspended in turbulent liquid. This is based on the fundamental information on the particle-liquid relative velocity, especially in the r
