A two-component LDV was used in a cold flow dump combustor model to obtain detailed mean and turbulence data for both swirling and non-swirling inlet flows. Large samples were collected to resolve the second and third order products of turbulent fluctuations with good accuracy. Particle interarrival time weighting was used to remove velocity bias from the data. The swirling flows, with and without vortex breakdown, exhibited significantly different mean flow and turbulent field behavior.
