| 摘 要： | 多孔射流作为流体运动的一种重要类型,在工程中具有非常广泛的用途。由于多孔射流各股水流之间的卷吸和掺混的存在,增加了流场的复杂性。长期以来研究人员从理论分析、实验测量和数值模拟方面对多孔紊动射流进行了大量的研究工作,目前已经认识了流场中的许多流动特性和流动机理。从数值模拟和实验研究两个方面,比较分析了国内外多孔紊动射流的研究现状和研究结果,评述了不同湍流模型以及不同实验测量方法对紊动射流的预测能力,讨论了存在的问题并对该领域的研究方向进行了展望。

| Abstract: | The multiple jets is an important type of fluid flow with its application in various engineering fields and a highly complex turbulent flow due to the action of entrainment and mixing of the high speed flow. These phenomena were observed in number of p~vious investigations in theoretical, experimental and numerical studies, and some structural features and flowing mechanisms are revealed. In this paper, from the aspects of the numerical simulation and the experimental study, the present study methods and results are analyzed, and the forecasting ability of both the different turbulence models and various measuring ways are summarized. In the end, some unsettled issues are discussed and the developing directions in this field are also pointed out. |
