Abstract
The rapid evolution of digital imagery and the fast growth of computational
power over the last ten years have contributed significantly in the development
and maturity of image-based diagnostic techniques for flow field characterization.
Of the several techniques that have evolved, particle image velocimetry (PIV) and
laser induced fluorescence (LIF) for velocity and concentratiodtemperature
determination, respectively, have reached a good level of maturity and thus
currently enjoy an increasingly level of popularity and acceptance by
experimental fluid dynamicists. The current paper focuses on PIV and LIF,
presenting their methodology and implementation for fluid flow characterization.
