流动可视化和热电线的测量技术被联合在喷气流动地和旋涡结构产生机制上调查尺寸的影响和标签的数字。不同尺寸和数字的标签产生的 Streamwise 旋涡从流动可视化图象被观察。与流动可视化结合了，热电线的测量给了各种各样的 tabbed 喷气流动的效果的量的卓见。在沿着半径方向和溪流的不同的生气的节的即时二部件的速度信号(纵、横向的速度部件) 有不同 tabbed 喷气嘴的明智的方向用热电线的风速表被测量。tabbed 喷气的平均流动域参数流动例如吝啬的速度，骚乱紧张，涡度被分析，有不同尺寸和数字的标签的效果与圆形的没有标签的相比喷气流动。这被揭示方位角的旋涡是的一系列相反旋转的 quasi-streamwise 旋涡，方位角的旋涡和双排的产生为混合 tabbed 的改进的原因狂暴的喷气流动。

英文摘要：

Flow visualization and hot-wire measurement techniques were combined to investigate the influence of the size and number of tabs on jet flow field and vortex structure generation mechanism. Streamwise vortices generated by the tabs of different sizes and numbers were ob- served from the flow visualization images. Combined with flow visualization, hot-wire measurement gave a quantitative insight of the effect of various tabbed jet flows. Instantaneous two-component velocity signals （longitudinal and transverse velocity components） at different cross sections along radius direction and streamwise direction with different tabbed jet nozzles were measured using hot-wire anemometer. Average flow field parameters of tabbed jet flow such as mean velocity, turbulence intensity, vorticity were analyzed and the effects of tabs with different sizes and numbers were compared with that of circular no-tab jet flow. It is revealed that the generation of a series of counter-rotating quasi-streamwise vortices, azimuthal vortices and double-row azi-muthal vortex are the reasons for mixing enhancement of tabbed turbulent jet flow.
