Numerical Simulation of Agitated Flow Field of Submersible Mixer Based on Computational Fluid Dynamics

The flow formulation is founded as console formulation first, and with the body-fitted coordinate system and standard k - epsilon turbulent model, the numerical simulation of the internal 3-D incompressible turbulent flow agitated flow field of submersible mixer is carried out by numerical simulation 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 simulation results and present some optimal methods.
