Experimental study of pulse characteristics of turbulent tube flow of a gas with solid particles

摘要

Distributions of longitudinal and transverse components of the intensity of velocity fluctuations of a carrying air in the presence of a disperse phase in the form of solid particles are obtained for the case of realization of a weakly dusted nonequilibrium flow in a vertical tube. The distributions showed that the presence of particles in the flow results in a decrease of turbulent fluctuations of velocity. The effect of suppression of fluctuations increases with an increase in concentration of particles, a distance from the tube wall and with a decrease in time lag of particles.
