A mixing flow in a cylindrical vessel agitated by a bubbling jet is measured quantitatively applying particle tracking velocimetry by the binary cross correlation method. Analysing hundreds of video frames by the method, instantaneous velocity distributions, particles paths and velocity fluctuations are measured in a relatively short time. Although a two-dimensional measurement are used in the present experiments, results such as particles paths and instantaneous velocity distributions could be discussed considering threedimensional factors.
