Gas Turbine Internal Air System Sealing Design

总而言之，该项目旨在了解蜂窝迷宫密封在内部空气系统中的传热和排放特性，特别是蜂窝定子。这将包括通过使用CFD和FEA软件来模拟密封设计来评估诸如离心力和热增长、侵入定子和运行参数等因素。2D和3D模型将与非耦合和耦合模型一起使用，以辨别蜂窝细胞内的物理现象。最终，该项目的最终成果应该是提供一种预测蜂窝电池热特性的方法，并考虑几个因素，以用于实际发动机应用。

In broad terms, the project aims to understand the heat transfer and discharge characteristics for honeycomb-labyrinth seals within internal air systems, with particular attention to the honeycomb stator. This will incorporate the assessment of factors such as centrifugal and thermal growth, incursion into the stator and operational parameters through the use of CFD and FEA software to model the seal designs. Both 2D and 3D models will be utilised along with uncoupled and coupled models to discern the physical phenomena within the honeycomb cells. Ultimately, the final deliverable of the project should be to deliver a method of predicting the thermal characteristics of honeycomb cells with consideration of several factors for use in a real engine applications.
