Abstract

Turbulence structures of downward blowing circular jet involving fine glass particles have been investigated to clarify the basic phenomena of turbulence motion in two-phase suspension flow. The three-beam laser Doppler anemometry, which had an appropriate signal processing system for the measurements of velocities with particle size discrimination, has been employed for simultaneous measurements of two component velocities of gas and particle phases. The velocity fluctuations in two-phase system was larger in the main flow direction than the direction normal to the main flow, while Reynold shear stresses of gas phase decreased in the whole region. This phenomenon of reduction of turbulence motion could be related to the correlation of fluctuation of two-component velocities of each phase.
