TRANSIENT SIMULATION OF SOLID PARTICLE DISTRIBUTION WITH BAFFLES DESIGN PARAMETERS IN A STIRRED TANK

배플 형상에 따른 교반기 내부 고체입자 분포의 비정상상태 해석

In the present study, a numerical simulations are investigated in a stirred solid/liquid system by using Eulerian multi-phase model. The transient flow field of liquid phase and distribution of solid particles are predicted in stirred tanks consisting of 4-pitched paddles impeller and baffles. The effects of number and width of baffles on the mixing time and the quality of solid suspension in a stirred tank are presented numerically. The result shows that the mixing time decreases as the width and number of baffles increase.
