碩士 === 國立交通大學 === 應用化學系所 === 92 === The fluted mixing element is one of many used mixing elements.For the mixing section , finite element method based on the Tadmor melting model was utilized. And carbon black was dispersed in the PP phase to investigate the mixing effect. This study aims to investigate the mixing effect caused by various types of geometry of fluted dispersive mixing elements by numerical simulation. In addition, the clearance between, the width of barrier flight barrier flight and barrel surface and helical angle of barrier flight were varied to investigate their effect on the mixing performance, including the stress and the residence time in the barrier region and the pressure variation at axial direction. In further , Searching the optimal geometry in fluted mixing element
