Novel Particle Image Velocimetry Methods for Visualization of Thrust Reverser's Flow Interactions

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review


This study presents the development of novel a Particle Image Velocimetry (PIV) system to visualise and evaluate reverse flow interactions with fan aerodynamics, in short, slim-engine nacelle designs applicable to the next generation of ultra-high bypass ratio (UHBR) aero engines. A novel miniaturised PIV system, that can be mounted inside a scaled jet engine model has been developed by utilising machine vision cameras, fibre optic laser coupling, and volumetric autocorrelation algorithms. As a result, the volume of the miniaturised camera system was reduced to 1.2% of a conventional PIV camera without a lens. In addition, a scanning panoramic stereo PIV system was used to investigate the external flow field. The working principles and the wind tunnel experiment results of the systems are presented in this paper.
