PIV에 의한 산업용 교반기내 Hcdrofoil 임펠러 형태에 따른 비정상 유동특성에 관한 연구

다국어 초록 (Multilingual Abstract)

Mixer are used in various industrial fields where it is necessary to intimately mix two reactants in a short period of time. However, despite their widespread use, complex unsteady flow characteristies of industrial mixers are not systematic investigated. The present study aimed to clarify unsteady flow characteristies induced by various impellers in a tank. Impellers are hydrofoil turbine and n대-hydrofoil turbine types. A high speed CCD camera and an Ar-Lon laser for illumination were abopted to clarify the time-dependent flow characteristics of the mixers. The rotating speed of impellers inereased from 6Hz to 60Hz by 6Hz, The maximum velocity around n대-hydrofoil impeller is than the hydro-foil type impeller. These tow types of turbine shows that typocal flow characteristics of axial turbine and suitable for mixing high-viscosity materials.
