Effect of adjacent impeller on mixing region of impeller in stirred vessel with two stage turbine impellers.

To evaluate the effect of an adjacent impeller on the axial mixing region of a turbine impeller in a stirred vessel with multiple-stage impellers, the mixing process of liquid was observed by the color reaction method at various distances between two-stage turbine impellers. The mixing region was measured by the mixing time method.No meaningful effect of an adjacent impeller on the scale of the mixing region was observed. Therefore, measurements of the scale of the mixing region in a stirred vessel with an impeller hold in one with multiple-stage impellers.
