| Abstract: | Mean and fluctuating radial velocities have been measured in the inipeller stream of a baffled, turbine-agitated cylindrical tank. Auto-correlation functions, energy spectra and amplitude probabilitv density functions of the radial velocity fluctuations were also obtained. In the vicinity of the impeller, the motion is distinctly periodic, with a time scale corresponding to nbN/60, where nb is the number of turbine blades and N is the rpm. The amplitude of the periodic component was found to decrease with radial distance from the inipeller tip and was used to correct the measured turbulence intensities. |
