自20世纪90年代零净质量流量射流作为一种实验室流动控制方法首次应用以来，引起了人们的广泛关注。ZNMF喷气机具有独特的特点，如紧凑的致动器，不需要外部空气供应，复杂的管道等，成为流体力学研究的热点课题。本文介绍了静止流体中ZNMF射流的发展现状、ZNMF射流与横流的相互作用及其在分离流控制中的应用。给出了ZNMF涡环/涡对的演化过程和ZNMF在流体和横流中的空间流动结构，以及关键参数的影响。最后，介绍了零负磁场射流在圆柱尾迹控制、翼型分离控制以及MAV/UAV气动力/力矩控制中的应用。
Since the zero-net-mass-flux (ZNMF) jet was first used as a laboratory flow control method in 1990’s, it has attracted much attention. The ZNMF jet has unique features such as compact actuator, no requirement for external air supply, complex piping, etc., and becomes a hot topic research subject in fluid mechanics. This review introduces the state of the art in the development of ZNMF jet in the quiescent fluid, the interaction of the ZNMF jet with the cross flow and its application in the separation flow control. The evolution of the vortex ring/pair and the spacial flow structure of the ZNMF in quicent fluid or cross flow are presented, as well as the key parameter effects. At last, the applications of ZNMF jet in the wake control of the circular cylinder, the separation control on the airfoil and the aerodynamic force or moment control on MAV/UAV are presented.
