Simulation of Laminar Mixing in Fractal Perforated Plate Static Mixers

Abstract:

This paper examines the performance of a new type of static mixer known as Fractal Plate Static Mixers. A simulation study was performed to investigate the pressure drop across different numbers of mixing elements (1, 2 and 3). The effectiveness of mixing was assessed by analyzing the coefficient of variation (CoV) of the flow within the range of 0 to 1. The value of CoV that approaching 1 is categorized as a total segregation, while close to 0 indicates a good mixing. The Reynolds number of the study was chosen between 500 and 2000 based on the unobstructed pipe diameter. Results showed that the mixing elements in the flow stream promote a non-laminar, turbulent-like flow which substantially enhances the mixing. By adding more mixing element, it was found that the flow mixing was enhanced in particular at lower Reynolds numbers. In spite of this advantage, the pressure drop was found increased in proportional to the number of mixing elements. This work presents an initial stage of ongoing work to develop a new type of static mixers that based on perforated plate.
