采用参数化的建模方法对两级四列某舰用涡轮冷却叶片进行了冷却结构的设计。通过参数控制复杂涡轮冷却叶片能够方便快捷地生成几何模型,并且为后期冷却结构的修改也提供了极大的便利,参数建模是气冷涡轮叶片设计方法进行工程化应用的前提条件。应用分块化结构网格构造复杂涡轮冷却叶栅进行网格分区时既要保证易于生成高质量网格,又要注意不能过多增加网格分区,增加计算误差。冲击冷却和气膜冷却等措菔能够有效保证叶片正常工作,蛇形通道加扰流肋片能够提高叶片的冷却效果。
This paper introduced blade cooling structure design process for two stage gas turbine vane using parameterized method. It was very convenient for complex gas turbine cascade geometry set up using parameterized method. It was also benefit for the model rebuilt at later period. Parameterized modelling method was the prerequisite of air cooling turbine engineering application. Mesh block partition number and mesh quality should be considered when using multi block mesh method on complex cooling structure blade. Impingement cooling and film cooling could protect blade effectively. Serpentine passage with turbulent ribs enhanced the rotor cooling effect.
