oppler anemometry measurement techniques. The time and length scales of turbulence were determined and ud to estimate the dissipation rate of turbulence energy. The levels of turbulence energy and dissipation are high near the turbine and decrea rapidly with increasing distance from the turbine blades. The turbulence in the impeller stream is mostly anisotropic clo to the blades. The results are compared with the findings of earlier investigations, and their implications for computational fluid dynamics (CFD) predictions of the flows are discusd.
