- Abstract:
- In this paper, the multi-reference frame(MRF ) and standard h - s turbulent model were used tosimulate the flow pattern and mixing characteristics in the stirred tanks with double layer straight impeller,double 45° inclined impeller and double layer straight and inclined combined impeller. The results showedthat double layer combined impeller can enhance the turbulence and mixing of the upper fluid and lower one inthe stirred tank.Moreover,compared with the double layer straight impeller， double layer combined impellercan save 37.91% of stirring power and reduce 50.48% of mixing time. Furthermore , compared with the feed-ing patterns from the fluid surface and the lower blade, the feeding pattern from the upper blade can obviouslysave the mixing time and improve the efficiency of mixing.
