Abstract：In order to solve the problem of extensive application in the mixing field, the position of the double-belt agitator and the hexagonal oblique disc turbo agitator was changed by the computational fluid dynamics(CFD)analysis method. Based on the Navier-Stokes equation and standard k-ε turbulence model, the flow field generated by the internal fluid of the stirred tank is numerically calculated to obtain the flow field data of the stirring blade at the stirring speed of 240 r/min. We analyzed the axial, circumferential, radial velocity vector of the agitator at the specific interface and its integrated velocity contour, and compared the flow field of the position change. The suitable industrial production paddle type for the upper double-helical paddle impeller blades was selected as the best combination of paddles. The combination of these paddles is helpful to improving the mixer in the application and development.
