Analysis of the Thermal Deformation of Turbine Blade Coupling Gas-heat-solid Field

  • 摘要: 叶片尺寸对涡轮机的工作效率影响很大,为了研究透平叶片在复杂工况下的热变形,建立了气-热-固耦合模型。通过改变冷却工质比,获得一系列的三维温度场和热变形分布。结果表明:叶片的热变形整体表现为从压力面向吸力面弯曲,纵向热膨胀显著,横向的变形较小,最大变形位于叶顶前缘。随着叶片表面温度降低,热变形对温度敏感度变差。在高温段可用纵向变形来近似代替叶片总变形。该模型可预测叶片热变形,为叶片尺寸设计和型面尺寸校正提供参考数据。
