Particle Image Velocimetry (PIV)

Particle Image Velocimetry (PIV) is an optical method of flow visualization used and research. It is used to obtain instantaneous velocity measurements and related properties in fluids. The fluid is seeded with tracer particles which, for sufficiently small particles, are assumed to faithfully follow the flow dynamics (the degree to which the particles faithfully follow the flow is represented by the Stokes number). The fluid with entrained particles is illuminated so that particles are visible. The motion of the seeding particles is used to calculate speed and direction (the velocity field) of the flow being studied.

GAIM use PIV in conjunction with scale models and/ or the experimental testing facility to fully visualise and quantify the flow system.
