機械的回転攪拌翼による液流れにおける乱流の特性

抄録

For a baffled vessel agitated by conventional disk turbine impellers with six flat blades, the liquid flows discharged by the impellers were measured using the particle tracking velocimetry (PTV) for the turbulent flows to be evaluated. The PTV measurements were comparable to those by the lasser Doppler velocimetry which has been often employed over other techniques for flow measurement. The geometry of the impeller and vessel having baffles was suggested to affect the turbulent flow level in the impeller discharge flow.
