Probing the spatial and temporal structure of turbulent combustion with tomographic PIV and high-speed imaging

Laser imaging techniques for probing the structure and temporal evolution of turbulent flows and flames are illustrated by simultaneous LIF imaging and 3-D velocity field measurements using tomographic PIV at a 10-kHz repetition rate. Rayleigh scattering measurements of transient flows at elevated pressure are demonstrated using a 100-kHz repetition rate pulse-burst laser.
