| 摘 要： | 本文借助数值模拟技术,通过气动热分析耦合计算研究了某型航空用涡轮第二级静叶在绝热及实心叶片耦合换热情况下的流道温度场分布,并分析了流场结构,特别是对叶片温度场分布结果进行了分析。通过对三维计算结果的分析表明,耦合计算得到的流场温度场分布更符合实际。耦合与非耦合计算的差别主要体现在温度场的不同上,进而导致了马赫数、压力场、波系及临界流量的不同。因此在气冷涡轮设计中使用多场耦合技术进行数值模拟是非常必要的。

| Abstract: | This paper studies one aeroengine's second stator on adiabatic and coupling situation with the numerical technology.It also analyses the flow structure,especially the temperature field of blade.Results show that more accurate temperature field is predicted by coupling method through 3D analysis.The main difference between coupling and non-coupling calculation lies in temperature distribution,and the Mach number,pressure area,wave,and transonic flux are also different.Therefore it is very necessary to use coupling numerical simulation method in air-cooling turbomachine design. |
