摘要

Abstract

The flow and mixing behavior of two miscible liquids has been studied in an innovative static mixer by using CFD

with Reynolds numbers ranging from 20 to 160. The performance of the new mixer is compared with those of Kenics

SMX

and Komax static mixers. The pressure drop ratio (

-factor)

coefficient of variation (CoV)

and extensional efficiency (

) features have been used to evaluate power consumption

distributive mixing

and dispersive mixing performances

respectively

in all mixers. The model is firstly validated based on experimental data measured for the pressure drop ratio and the coefficient of variation. CFD results are consistent with measured data and those obtained by available correlations in the literature. The new mixer shows a superior mixing performance compared to the other mixers.
