Abstract

The turbulent structure of a liquid-solids two-phase jet has been experimentally investigated to examine a model application for the particle kinetic eddy viscosity in a turbulent two-phase flow. The confined jet flowed in the gravitational direction at the Reynolds number of the inner jet 1.1 × 104. Spherical glass particles of 486 were loaded into the inner tube at a volume fraction of 1 %. The flow fields were measured by a laser Doppler velocimeter, with a particle size discrimination. In the developing region of the shear layer, measurements revealed a a decrease in the turbulent kinetic energy and the turbulent shear stress of liquid phase involving solid particles. The model based on the characteristic time scale ratio of turbulent two-phase flow confirmed a good agreement with experimental results.
