Abstract

Particle Image Velocimetry (PIV) was used to measure the gas-velocity distribution at the exit of a 0.79cm ID pipe (Re = 680), both in cold flow and within a premixed flame (Φ= 1.06). To perform PIV, a double-pulsed laser-light sheet was used to illuminate the particle-seeded flow, and the particle- scattered light was photographed. The photograph was interrogated on an automated system, producing two measured velocity components (u and v) on a regularly spaced (0.2 mm) grid with a spatial resolution of 0.5 mm over the entire photographed region. The radial distribution of the axial velocity, v(r), and the gradient, dv(r)/dr, 0.5 mm from the exit of the pipe in the cold flow compared favorably with that predicted by Poiseuille’s theory. The velocity in the unburned gas ahead of the laminar flame was measured successfully as well.
