Gas Turbine Internal Air System Sealing Design

从广义上讲，该项目旨在了解内部空气系统中蜂窝迷宫密封的传热和排放特性，特别关注蜂窝定子。这将通过使用CFD和FEA软件对密封设计进行建模，对离心力和热增长、侵入定子和操作参数等因素进行评估。二维和三维模型都将与非耦合和耦合模型一起沿着使用，以辨别蜂窝单元内的物理现象。最终，该项目的最终交付成果应该是提供一种预测蜂窝单元热特性的方法，并考虑到用于真实的发动机应用的几个因素。

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.
