Abstract
With the growing global emphasis on environmental protection, energy conservation, and emission reduction, along with rapid advances in precision machinery and manufacturing technologies, energy-efficient multi-blade centrifugal fans have become a key research area worldwide. These devices, commonly referred to as multi-blade centrifugal fans, utilize an impeller with multiple blades to transport air or gas, operating on the same fundamental principles as conventional centrifugal fans. Due to their ability to deliver high flow rates with high efficiency and stable performance, they are widely used in ventilation, air conditioning, and industrial applications. This paper provides a comprehensive review of recent advances in the research and development of multi-blade centrifugal fans. It covers key aspects of component design and optimization, including the impeller, volute, collector, and rim clearance. The review also addresses critical issues, including rotating stall, vibration, noise generation, and material selection. Furthermore, it highlights emerging perspectives, including the application of entropy production theory to elucidate flow mechanisms, strategies for performance optimization, advanced technologies for material innovation, and protective devices to enhance operational reliability and functionality. This review provides guidance for future research and development aimed at improving the efficiency and performance of multi-blade centrifugal fans across diverse applications.
