摘要
Particle Image Velocimetry (P.I.V.) technique has been used in mechanically agitated tank equipped with a Rushton turbine to analyse the flow field in terms of mean flow, turbulence (random fluctuation) and pseudo-turbulence (fluctuation induced by the periodic motion of the blades). From instantaneous velocity field taken in a plane with at given angles relative to the position of the blade, it is possible to derive spatial two-point velocity correlation functions in order to deduce integral length scales of turbulence and local dissipation rate of turbulent kinetic energy.
