| dc.description.abstract | The Industrial Mixers are used in various industrial fields where they are necessary to effectively mix two or more material components in a short period of time. However, despite their wide use, complex unsteady flow characteristics of industrial mixers are not yet systematically investigated. The present study aims to clarify unsteady flow characteristics induced by various impellers in a tank. Impellers are pitched blade turbine(PBT) types, Screw type and Rushton turbine type. To investigate the flow characteristics and mixing efficiency, PIV,CFD and concentration measurement were carried out systematically. PIV measurement gave clear description of 3-D complex mixing phenomena and CFD analysis suggested time-averaged flow patterns not shown in PIV result. Concentration measurement technique was adopted to quantify the mixing efficiency for various operation and type condition. In conclusion, Rushton type gave the more satisfactory result when its impeller is located at middle height. | - |
