Investigations of liquid flow velocity in a vibromixer using stereo PIV anemometry
Languages of publication
This paper presents the results of investigations of liquid flow in a vibromixer with a single, reciprocating disc. Measurements were conducted using Particle Image Velocimetry (Stereo PIV). Liquid circulation was analysed for two cases: in a whole mixing vessel; in selected zones of intensive flow, e.g. in a gap between the disc and the tank wall. Results of measurements are presented as vector and contour maps of flow velocity distribution. Also, curves illustrating changes of flow for various instantaneous disc positions are shown. Results presented in this work can be used in practice during designing and design optimization of vibromixers applied in the production of multiphase systems and also for the creation of theoretical foundations for the dispersing of phases using mixing equipment of this kind.
