Particle Image Velocimetry (PIV) is a non-intrusive optical technique that utilises tracer particles and high-speed imaging to capture and quantify fluid motion. By illuminating seeded particles in a ...

Experimental studies of flow velocity fields have been greatly advanced by the development of optical techniques It has been recognized that multipoint measurements can be achieved by recording the ...

Measuring the velocity field of a fluid flow, such as air or water, allows for greater feedback and control, something that could boost the performance and fuel-efficiency of aircraft. A research ...
