Modulation of Turbulence by a Dispersed Phase

The results of an earlier investigation that demonstrated the significance of the particle diameter/fluid length scale ratio in determining whether or not the addition of a dispersed phase would cause an increase or decrease in the carrier phase turbulent intensity are extended to radial locations other than the centerline. Presently, it is shown that similar trends are valid except the results become less correlated approacthing the wall for the case of pipe flows. The results for jets are independent of radial location. It is also shown that other possible non-dimensional parameters do not correlate the data as well.
