Current work at Cranfield University has developed a test rig and PIV measurement capability for measuring the highly distorted flow field at the exit of a curved intake duct. The overall aim of the research is to further develop innovative measurement methods for complex and podded engine intake systems. The research will focus on two main aspects: time resolved PIV for complex intakes and investigating fundamental aspects of applying PIV to short podded intakes. The research will include application of PIV for representative complex S-duct intakes on the Cranfield test rig as well as the development of methods for the analysis of unsteady TR-PIV data. The work will also include CFD simulations to refine the experimental arrangement for measurements in different regions of the duct. The research will also address the fundamental aspects of applying PIV and advanced measurements to short podded intakes in a wind tunnel. The aim is to identify and design a viable experiment arrangement in collaboration with a post-doctoral researcher.

克兰菲尔德大学目前的工作已经开发出一种测试装置和 PIV 测量功能，用于测量弯曲进气管道出口处高度扭曲的流场。该研究的总体目标是进一步开发复杂的吊舱式发动机进气系统的创新测量方法。该研究将集中在两个主要方面：复杂摄入量的时间分辨 PIV 和研究将 PIV 应用于短荚摄入量的基本方面。该研究将包括克兰菲尔德试验台上代表性复杂 S 管道进气口的 PIV 应用以及非稳态 TR-PIV 数据分析方法的开发。这项工作还将包括 CFD 模拟，以完善管道不同区域测量的实验安排。该研究还将解决将 PIV 和先进测量应用于风洞中短吊舱进气口的基本问题。目的是与博士后研究员合作确定和设计可行的实验安排。
