Numerical Modeling of Vortex-Induced Heat Transfer Enhancement with a Double-Wing Vortex Generator

This study investigates a novel double-wing vortex Generator for enhancing heat transfer efficiency compared to conventional rectangular vortex generators. In electro-mechanical systems, effective heat dissipation relies on vortex formation over heated surfaces, where vortex strength significantly influences thermal performance. While traditional vortex generator designs have been extensively studied, such configurations exhibit inherent limitations, necessitating further innovation for performance enhancement. The proposed configuration is evaluated at attack angles ranging from 0° to 90°, with numerical simulations conducted using ANSYS Fluent to analyze critical parameters, including wing angles and main section length. Numerical solutions of the conservation equations demonstrate substantial improvements in both thermal and flow efficiencies. The results indicate an 18.67% increase in the Nusselt number, an 11.43% rise in the coefficient of drag, and an overall thermal-hydraulic performance parameter of 1.247, surpassing the performance of the conventional rectangular counterpart. The study provides a comprehensive evaluation of flow and thermal characteristics, particularly focusing on downstream flow behaviors. These findings highlight the potential of the proposed design for improving heat transfer performance in thermal management applications.
