    Static mixers are becoming increasingly popular because they are energyefficient, cost-effective, and easy to maintain. Mixing is an essential unit operation in many chemical industries. In this study, a modified high efficiency vortex static mixer was used to examine laminar flows in a rectangular duct. To encourage fluid rotation and improve mixing with heat transfer, the modified high efficiency vortex set was rotated by angles of 0 degrees, 5 degrees, 10 degrees, 20 degrees, 25 degrees, and 30 degrees. The Reynolds number varied from 3000 to 8000. The outcomes demonstrated that the performance of the mixing was significantly impacted by the modified high efficiency vortex set. The highest mixing efficiency was achieved with a rotation angle between 15 degrees and 20 degrees. Furthermore, the rotations reduced pressure loss in the system and enhanced heat transfer performance, by creating vortices. These results show how modified high efficiency vortex static mixers can improve mixing and heat transfer efficiency in turbulent flows, with prospective utilization across diverse chemical sectors.

    CFD STUDY OF A DUAL-PASSAGE SOLAR COLLECTOR WITH LONGITUDINAL AND TRANSVERSE BAFFLES FOR ENHANCED THERMAL PERFORMANCE
    (Vinca Inst Nuclear Sci, 2023) Amraoui, Mohammed Amine; Alkhafaji, Mohammed Ayad; Abdullaev, Sherzod; Zearah, Sajad A.; Akgul, Ali; Jarrar, Rabab; Shanak, Hussein
    The focus of this research is to investigate the heat transfer performance of a solar flat plate collector by utilizing CFD simulation. To accomplish this, a 3-D model of the collector with an air inlet was created using ANSYS Workbench, and the grid was generated through ANSYS ICEM, ANSYS FLUENT, and ANSYS CFX were then used to obtain comprehensive results. The primary objective of this study is to enhance the efficiency of the solar collector by introducing two fluid-flow paths and comparing the results with those reported in existing literature. These findings will aid in the development of advanced solar collector designs and promote sustainable use of solar energy. Furthermore, the insights gained from this study may inspire further research in the renewable energy technology field. Overall, this research explores the potential of improving the performance of solar flat plate collectors and sheds light on how the use of CFD simulation can facilitate the development of innovative and sustainable energy solutions.
