Abstract

The numerical simulation of the flow field generated by dual impellers in glycerol was carried out by using CFD method and laminar flow model. The flow field structure of four combinations of impellers under different spacing and constant rotation speed of 200 rpm in the stirred tank is obtained, and axial and radial velocity vectors and velocity distribution curves are compared and analyzed. The results show that when the distance between layers is greater than or equal to T / 2, the flow pattern of the flow field is parallel flow, and the distribution of the two straight blades is the best. When the distance between layers is less than T / 3, the flow pattern is connected flow,at this time, the combination of the run-off impeller under the axial propeller is the best.
