摘要

摘要: 紧邻电弧喷涂枪喷嘴产生的喷射尾流对生成涂层的性质有着显著的影响.采用计算流体力学（CFD）和纹影摄影技术阐明了喷射尾流的性质.纹影图像的检查结果显示，尾流的性质和宽度取决于用于热喷涂的丝材的方向.通过CFD方法，观察到激波在喷嘴孔口之后迅即形成,然后在下游尾流中衰减.

Abstract: The jet plume formed immediately adjacent to the nozzle of an arc spray gun has a significant effect on the properties of the resultant coating. This study applied the computational fluid dynamics (CFD) and the Schlieren photography to elucidate the properties of jet plumes. The Schlieren images examined revealed that the properties and widths of the plume depend on the direction of material wires for thermal coating. Through the CFD approach, we observed the formation of shock waves immediately after the nozzle aperture and damping of the shock waves in the downstream plume.
