Numerical Analysis of Agitated Flow Field of Submersible Mixer

Abstract:

The flow formulation was founded as console formulation, and with the body-fitted coordinate system and standard k - ε turbulent model, the numerical analysis of the internal 3-D incompressible turbulent flow of the agitated flow field was carried out by CFD software Fluent. The results showed that: the mixer impeller produced vortex jet flow, the constant velocity lines advanced as ellipse, the velocity along the centerline are larger than others, and utilized volume flow to transport the liquid. And, by changing some design parameters of mixer impeller, we can compare and analyze the numerical analysis results and find that: for the same impeller diameter, the mixer impeller whose hub/tip radius ratio is smaller has larger advancing speed in the agitated flow field, and the advancing speed is more evenly distributed, so the overall effect is better. Therefore, we should select the hub diameter of the submersible mixer properly.
