Abstract
The fluid flow in stirred tank with dual six-blade Rushton turbine was numerically simulated using fluent software. The turbulent model and sliding meshes were used in the simulation. The effects of the span of the impellers on the fluid flow were analyzed.The flow structure of stirred tank and power consumption was obtained,and compared with literature test results. The research indicates that the position of impeller is main influencing factor for flow structure in the stirred tank, parallel flow, merging flow and diverging flow were obtained by changing the position of impellers, vortex position and velocity distribution were also predicated successfully. Power consumption of three kinds of flow pattern is very difference,power consumption of parallel flow is the largest.关键词
