Flow Characteristics about Industrial Agitators Impeller Shape by CFD

전산유체역학을 이용한 산업용교반기의 Impeller형상에 따른 유동특성

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 agitators are not systematically investigated. The present study alms for clarify unsteady flow characteristics induced by various impellers in a tank. Impellers are pitched blade turbine(PBT) types, Screw type and Rushton turbine type. In this study flow characteristics of the impeller using CFD. The rotating speed of impellers fixed about 100RPM. These three types of Impeller show that typical flow characteristics of axial turbine and suitable for mixing powder
