Abstract

Anchor mixer is frequently used for mixing of viscous liquids. In the present work, a novel mixer for mixing of viscous liquid has been introduced and its efficiency was compared with anchor mixer using computation fluid dynamics (CFD) method. In this comparison, velocity vectors and counters, velocity profile and shear stress have been compared for two agitators. In addition the MIXING TIME in the tank has been investigated by injecting a tracer and considering the time variation of tracer concentration in three arbitrary points. The results show that in both cases homogenization in the lower region of the tank obtains faster than the upper region. The novel mixer produces more proper velocity profile in vertical and radial directions. This agitator, also, gives higher shear stress which results better TURBULENCE and homogeneity so that the MIXING TIME is about 50% less than for anchor mixer.
