本文旨在研究非对称狭缝对合成射流流动特性的影响。本文通过实验和数值模拟，研究了二维合成射流与非对称鸟嘴缝的流动特性之间的关系。结果表明，在长喙的情况下，由非对称狭缝诱导的不同x方向位置的涡对在喙的相对侧产生了大尺度的环流区域。研究还表明，合成射流的流场取决于不对称的缝喙长度;相反，连续射流与不对称的缝喙长度无关。
The purpose of this paper is to elucidate the influence of an asymmetric slot on the flow characteristics of synthetic jets. In this study, the relation between flow characteristics of two-dimensional synthetic jets and beak-shaped asymmetric slots is investigated experimentally and numerically. Results clarify that the vortex pair with differentx-direction locations induced by the asymmetric slot produces a large-scale circulation region on the opposite side of the beak in the case of long beaks. It is also demonstrated that flow fields for synthetic jets depend on asymmetric slot beak length; in contrast, continuous jets are independent of asymmetric slot beak length.
