| | Two ONERA engineer-researcher teams - one of experimental aerodynamicists, the other data processing experts specializing in image processing, have together developed the FOLKI*-SPIV software for high-speed processing of sequences of PIV images (Particle Image Velocimetry).... The flow takes off at the top of a bent slope : the PIV shows the speed field at all points of the observation window. (below : close-up of the rectangle above) * PIV (Particle Image Velocimetry) is an experimental technique that allows the speed fields of fluids to be measured by sowing the fluid with small particles that are imaged at a very high rate with high-speed cameras coupled to a laser flash. * The FOLKI algorithm family uses graphic processing units (GPU) that make it possible to reach - for some types of applications - computing powers that are much greater than those of the processors that are usually used.... |
