High-Speed Particle Image Velocimetry System for Aerodynamic Applications

当前提案的目标是获得一个能够在各种空气动力学应用中对速度场进行高速，二维和三维立体测量的粒子图像测速系统。所选择的系统被选中用于由柏林工业大学空气动力学主席发起的几个研究项目的多价速度测量。将使用该测量系统的研究项目包括：飞机机翼边界层分离控制执行器的优化、湍流分离流的低频动力学研究以及多体长航时飞机的空气动力学。

The objective of the current proposal is to procure a particle-image velocimetry system capable of high-speed, two- and three-dimensional, stereoscopic measurements of the velocity field in a variety of aerodynamic applications. The chosen system was selected to enable polyvalent velocity measurements for several research projects initiated by the Chair of Aerodynamics at TU Berlin. Examples of research projects in which the measurement system will be used are: the optimization of actuators for boundary-layer separation control on aircraft wings, the investigation of low-frequency dynamics in turbulent, separated flows, and the aerodynamics of multi-body, long endurance aircrafts.
