AN EXPERIMENTAL STUDY OF A TURBULENT ROUND TWO-PHASE JET

The effect of solid particles on the flow structure of an axisymmetric turbulent incompressible jet has been studied. A two-color laser anemometer was used to measure the mean and fluctuating velocity components along the axial and radial directions as well as the corresponding component of the shear stress. 50 mu and 200 mu glass beads were used. Results for the 200 mu case are presented for moderate mass loadings (mass ratio = 0.8, volumetric ratio = 3.5 x 10(-4)) which indicate significant influence of the solid phase on the flow structure. Results for the 50 mu case are reported elsewhere.(1) When compared with the single-phase measurement, the spread rate of the two-phase jet was found to be smaller and a lower level of turbulence was observed.
