Abstract
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 μ and 200 μ glass beads were used. Results for the 200 μ case are presented for moderate mass loadings (mass ratio = 0.8, volumetric ratio = 3.5 × 10-4)which indicates ignificant influence of the solid phase on the flow structure. Results for the 50 μ. 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.
