摘要

Installing vortex generators within heat transfer channels is one of the effective methods to enhance the heat transfer rate of fluids in pipes and passages. This approach holds significant importance for alleviating global energy constraints and achieving efficient energy utilization. By inducing fluid rotation around an axis, vortex generators can form vortices within pipes, thereby improving heat transfer efficiency and becoming a key focus in current energy-saving research. Despite extensive research on vortex generators in recent years, comprehensive reviews and summaries of their structures and types remain relatively scarce. This review systematically organizes the progress in traditional wing angle vortex generator research and focuses on comparing the heat transfer performance of various novel structures under different Reynolds number conditions. It aims to provide a comprehensive evaluation of the structural characteristics and application effectiveness of vortex generators, offering theoretical references and research insights for the subsequent development and optimization of related technologies.
