Abstract

Unsteady flow and the interface distribution in the stirred tank are studied by the large eddy simulation and multiphase flow model. The result shows that the two-phase interface starts from the paddle. Finally inverted cone interface is generated by the screw move. With mixing time passing by, the interface rotates with the paddle. Centrifugal effect is more obvious along with the speed rise. There is an apparently circulation area among the blades. Velocity near the blade tip is high. And a large number of small vortexes are formed because of the strong turbulence. Then fuels around are carried to other areas by the vortex motion. There are contrary velocity peeks between the hub and the blade tip. And with the speed increasing, difference between the radial velocity speeds becomes larger. Therefore, apparently main circulation area is generated between the hub and the blade tip.
