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 (Z-factor), coefficient of variation (CoV), and extensional efficiency (α) 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...

Abstract
The main objective of this study is a numerical simulation of flow and mixing behavior of two miscible liquids in a new static mixer over the Reynolds number in the range of 20-160. The performance of the proposed static mixer has been compared with the well-known three different static mixers namely, Kenics, SMX, and Komax. Pressure drop ratio (Z-factor), a coefficient of variation (CoV) and extensional efficiency (α) characteristics were, respectively, used to evaluate power consumption, distributive mixing and dispersive mixing performances in all static mixers. Since there are no experimental data for examined mixers, firstly, the CFD model was validated with measured data of the...
