Adjustable flow ejectors: research status and development trends

Abstract

Ejectors serve as crucial components in circulation systems within various industrial applications. Traditional ejectors featuring fixed structures exhibit limited adaptability to operating conditions, thereby restricting the system's performance. In response, adjustable flow ejectors (AFEs), featuring adjustable structures or supplementary nozzles, have been developed. However, the research landscape of AFEs is characterized by cross-domain technology diffusion, resulting in fragmented technological pathways that significantly hinder their rapid advancement. This study utilizes bibliometric methods to delve into the structural attributes, optimization and control strategies, and diverse application requirements of AFEs. Furthermore, this paper highlights the strengths and constraints, identifies current technological bottlenecks, and outlines future development directions, thereby fostering innovation and progress in AFE technology.
