AB This paper investigates the influence of rheological and geometrical properties on flow structures generated within a KENIC static mixer. The primary objectives are to examine the impact of these factors on fluid flow characteristics, particularly low-pressure conditions and mixing efficiency. To exanimate the performances of the different shapes, several parameters have been considered which consist on mixing index, thermal mixing index, hydrodynamic behavior and the probability density function. The investigation extends to encompass both Newtonian and non-Newtonian fluids, emphasizing Reynolds numbers ranging from 10 to 80. Comparative analyses are conducted against a conventional static mixer configuration. However, this investigation has been done with a numerical simulation using Ansys 20. Through comprehensive numerical simulations, the study highlights the significance of rheological and geometrical factors in shaping flow behaviors. The findings underscore the superior performance of the KENIC static mixer's designated configuration, denoted as KMSFH, when contrasted with alternative scenarios. The improved performance is observed across various flow conditions, showcasing enhanced mixing efficiency and lower pressure losses. Overall, this study found that the KMSFH showed a better performance with 99% than the other suggested mixers.
