Abstract
Industrial Agitators are used in various industrial fields where they are necessary to intimately mix two reactants in a short period of time. However, despite their widespread use, complex unsteady flow characteristics of industrial mixers are not systematically investigated. The present study aims for clarify unsteady flow characteristics induced by various impellers in agitator's tank. Impellers are Pitched blade turbine(PBT) types, Screw type and Rushton turbine type(RUT). In this study is numerical analysis of the Industrial agitator's Impeller types. The rotating speed of impellers fixed about 100RPM. Numerical analysis results show that differential flow characteristics of each type Impeller and Rushton turbine type(RUT) is suitable for mixing powder.
