The proposed research project, to be undertaken in collaboration with Pratt and Whitney Canada, aims to improve our understanding of the fundamentals of the three-dimensional flow fields in the inter-turbine duct and lobed mixer components of gas-turbine engines. This objective will be achieved through an investigation based on systematic variations of the geometric and flow parameters that are deemed to dominate the flow development in these engine components. The study will make synergic use of experimental and computational techniques to execute a test matrix with a relatively large parameter set while achieving the desired spatial and temporal resolution of the flow fields in question. Improved understanding of the fluid dynamics in these engine components will provide the foundation for their further optimization towards reduced size and improved aerodynamic performance, which will support the broader goal of designing gas-turbine engines with lower weight, reduced size, and greater efficiency.

这项拟议的研究项目将与加拿大普惠公司合作进行，旨在提高我们对燃气涡轮发动机涡轮间导管和叶状混合器部件三维流场基本原理的理解。这一目标将通过一项基于几何和流动参数系统变化的研究来实现，这些参数被认为是这些发动机部件中流动发展的主导因素。该研究将协同使用实验和计算技术来执行具有相对较大参数集的测试矩阵，同时实现所讨论的流场的所需空间和时间分辨率。提高对这些发动机部件流体动力学的理解，将为进一步优化发动机尺寸和改善气动性能提供基础，从而支持设计重量更轻、尺寸更小、效率更高的燃气涡轮发动机的更广泛目标。
