Particle Image Velocimetry on a Turbulent Jet

Abstract: The goal of the present paper is to set up, test and validate a home-made high-speed imaging system for investigating low-speed aerodynamic flows. The imaging setup includes a high-speed digital camera, a continuous wave laser and related optics. The setup has been optimized for: a) Flow visualization b) Particle Image Velocimetry based on an open-source code After optimizing the experimental setup, tests were performed on an axisymmetric jet. Based on the results obtained, the limits and potential of the present setup are discussed, and suggestions for possible improvements are given.
