TURBULENCE IN IMPELLER STREAM IN A STIRRED VESSEL

[摘要] References(7)Cited-By(10)In the impeller stream in a baffled six-flat-blade agitated cylindrical tank, radial, tangential and axial components of mean and fluctuating velocities were measured with a multi-electrode spherical probe based on electrochemical reaction controlled by diffusional mass transfer rate. The impeller stream flow field is characterized satisfactorily by turbulent statistical values about the velocity such as turbulence intensities, one-point double and triple correlations, and power spectrum.
