Abstract
The agitator is an important industrial instrument widely used for mixing various solutions in the industrial field. In this study, the optimized design of the helical ribbon type impeller, which is mainly used for the stirring of the high viscosity solution, is carried out by CFD analysis. For this purpose, an index for evaluating the agitation performance is newly defined and an optimization design process is performed through a multiphase computational fluid dynamic analysis. From these results, it is understood that the stirring performance is maximized in the case of the helical ribbon impeller under given operating conditions when the width is 7.5 mm, the height is 160 mm and the turn is 1.
