【 摘 要 】

Stirred tanks are widely used for mixing to pseudo-plastic fluids in chemical, food and many processing industries. Impeller stirred tanks play a very important role throughout process industries. Design of such systems and the effective control of the relevant processes require an understanding and prediction of the flow characteristics. One technique to develop high efficiency of this fluid production such as bioethanol is to reduce the stagnant or dead zones formation phenomena inside the stirred tank using computational fluid dynamics. The results have shown that the new impeller design as dependent variables were able to eliminate the dead zone formation related with the independent variables such as power number P0 , pumping number N q, wall shear stress τ, mixing time τ, and average effective viscosity μ.
