In the paper were carried out experiments on two-dimensional nozzle flow with and without incoming swirling in a low-speed wind tunnel.

本文介绍了在低速射流风洞上开展的二维喷管来流带旋涡的模拟实验。

A new type of nozzle generating swirling-abrasive water jet has been designed and the numerical method is employed to analyze the characteristics of the jet flow in the nozzle.

设计了一种水垫式旋转磨料射流喷嘴，并对其内部流场流动特性进行了数值研究。
