EFFECT OF THE PARTICLES CONCENTRATION ON FLUCTUATING VELOCITY OF THE DISPERSE PHASE FOR TURBULENT PIPE FLOW

Resumo

This paper presents the results of an experimental study of the solid particles fluctuation velocities distributions for case of their motion in the downward turbulent pipe flow. The glass particles with mean diameters of 50 µm and 100 µrn were used as a disperse phase. The particles mass loading was varied in the range M =0-1.2. The obtained results clearly showed that the particles fluctuation velocities are strongly depended on its mass loading.
