Abstract

Based on the flow patterns of cylindrical vessel, the flow patterns of conical vessel, spherical vessel, rectangular vessel and cylindrical vessel with baffles were visualized by a trace method using aluminum powder. In addition, the correlations of the critical circulating frequency for mixing were derived from the experimental results. The conical and spherical vessels which have circular cross sections were same effective as cylindrical vessel for the shake mixing due to developing the rotational flow. Both a rectangular vessel and a cylindrical vessel with baffles should not be adapted for shake mixing because of not developing rotational flows in these type of vessels.
