Abstract

We demonstrate a new imaging technique for velocity measurements in particle-laden flows. The technique, particle vaporization velocimetry, is a form of flow tagging based on laser vaporization of absorbing particles at defined locations in the flow. The locations of these tagged regions are then interrogated after a known delay to determine the convective velocity. Results are presented for vaporization of carbonaceous (soot) particles in a nonreacting gas jet and a hydrocarbon flame, with interrogation provided by either elastic scattering or laser-induced incandescence from the soot. The long lifetime of the tagged soot regions (>2 ms) allows measurements to be made over a wide range of velocities.
