A synthetic jet actuator is a fluidic device that produces a jet flow by the periodic ingestion of fluid into and expulsion of fluid out of a cavity across an orifice. Since such a mechanism transfers linear momentum to the fluid without introducing a net mass into the system over an actuation cycle, the synthesized jet is also termed a zero-net-mass-flux jet. Over the last two decades, synthetic jets have been the subject of intense research. It has been shown that the geometric parameters of a synthetic jet actuator can strongly influence the flow characteristics and performance of synthetic jets. The aim of this paper is to provide a comprehensive review of the influence of the geometric parameters of a synthetic jet actuator on the characteristics and performance of synthetic jets. These parameters include the height and diameter of the cavity and the orifice and the shape and edge configuration of the orifice.

几何参数对合成射流的影响：综述

合成射流致动器是一种射流装置，它通过周期性地将流体吸入腔体并将流体穿过孔口排出腔体来产生射流。由于这种机制将线性动量传递给流体，而不会在驱动周期内将净质量引入系统，因此合成射流也称为零净质量通量射流。在过去的二十年里，合成喷气机一直是深入研究的主题。已经表明，合成射流致动器的几何参数可以强烈影响合成射流的流动特性和性能。本文的目的是全面回顾合成射流致动器的几何参数对合成射流特性和性能的影响。
