摘要: 针对燃气轮机动力涡轮工作环境恶劣、承受负荷大等特点，为保证动力涡轮可靠性运行、满足强度要求，对动力涡轮静子(包括第三、四机匣，第三、四级导向器等零部件)在工作时的表面温度场进行了详细的数值计算。计算过程中，通过沿叶片径向设置扇形段并在扇形段的端面处设置循环对称边界条件，减少了单元与节点数目，简化了计算、节省了计算资源。计算结果可以用于动力涡轮部件的强度计算分析和冷热态尺寸链计算，对燃气轮机的结构强度设计和热力性能校核有一定的参考作用。
Abstract: In order to ensure the reliability and strength of the power turbine, the surface temperature field of the power turbine stator (including the third and fourth casings, the third and fourth stage guides, etc.) is calculated in detail. In the calculation process, the number of elements and nodes is reduced, the calculation is simplified and the computing resources are saved by setting sector section along the radial direction of blade and setting circular symmetric boundary conditions at the end of sector section. The calculation results can be used for strength calculation and analysis of power turbine components and dimension chain calculation in cold and hot state, which can be used as a reference for structural strength design and thermodynamic performance check of gas turbines.
