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...
