摘　　要：为探究基于时间推进的通流方法在叶轮机械设计分析中的应用潜力,报告了国内外相关研究现状,详细阐述了该方法在应用过程中的若干关键问题,包括:叶片堵塞的几何描述、叶片力的模拟、叶片前后缘间断问题的处理和激波的捕获等,并对不同模型进行了比较。总结可知,相比传统通流方法,该方法具有捕捉激波,适应堵塞,流场模拟更为精细以及计算扩展性良好等诸多优点,在先进航空发动机或燃气轮机的部件设计和分析、整机稳态、过渡态性能模拟中,都具有相当的优势与应用潜力;同时尽管该方法的研究取得了很大进展,但在上述若干关键问题上仍有提高空间。通过进一步的发展与完善,该方法有望成为叶轮机械设计和分析的标准工具。Aiming to have an exploration on application potential of the throughflow computation method for turbomachines based on the time marching,the research progress home and abroad is concluded,and several key issues of application of this method are generalized,including geometric description of blade blockage,simulation of blade force,discontinuity problems in blade leading and trailing edges,and shock capture.Different computation models are also compared.It is summarized that the throughflow computation method based on the time marching has many advantages compared to the traditional throughflow method,and thus has the potential to be a competitive tool in advanced gas turbine engine components design and analysis,as well as in total engine steady and transient state simulation.This method is expected to have much more improvements in the aspects mentioned above,although it has achieved great progress.It is believed that this method will be adopted as a new standard tool in turbomachinery design and analysis with further developments and improvements.
