BackgroundA bit about me
Ben FalconerCame to Warwick 2006Computer and Information engineeringMEng project
Project based around PIVCurrent experiments taking place in
Farnborough
Particle Image VelocimetryUsed to map the velocity
of a flow field cross sectionLaser creates a light
sheet through the flowCameras take quick
series of imagesCorrelation yields
velocitiesMultiple cross sections
create a 3D map of the flow field

ProcessingResolve stereoscopic images
Produce a 3D plot of the field from two stereoscopic images.
Cross-correlationFind movement of each
particle within the 3D plotsProduce a velocity mapping
for the planePlane stitching
Join each plane mapping to form a full area mapping Image courtesy of
