| 摘 要： | 射流-横向流干涉流场中存在三种不同的涡运动:附着涡,尾迹涡和剪切涡。本文利用荧光丝和七孔探针作为流场观测手段,研究了干涉流场中涡的形成机理及其相互干扰。此外,文中还分析讨论了影响流向涡的发展和衰减的主要因素。

| Abstract: | Three different vortex systems exist in flow field underinteraction of a jet with a crossflow.bound vortex,wake vortex and shear vortex.In this paper,the mechanism of vortex formation is suggested,and interference among vortexes is investigated on the basis of observation and measurement by fluorescent filament method and seven-hole probes.And finally,the major factors which influence the devolp-ment and decay of streamwise vortex are also analysed and discussed. |
