The techniques of particle-streak and pulsed-laser velocimetry were investigated to determine their applicability in obtaining two-dimensional velocity information. As a result of these investigations, a third technique—scanned-laser velocimetry—was developed. In each method particles are seeded into combusting and noncombusting flows and their movement within a sheet of laser light photographically recorded. Analysis of the particle tracks provides velocity as well as valuable flow-visualization information.
