An Evaluation on the Use of Large, Hollow Micro-Balloons as LDV Seed Particles,
Abstract
A combined theoretical and experimental study has been conducted to evaluate the effectiveness of using large, hollow micro-balloons as LDV seed particles. The study has focused on the ability of phase Doppler systems to size hollow micro-balloons, the ability of large micro-balloons to respond to high frequency, spatial and temporal flow field variations, and the overall advantages and disadvantages of using large micro-balloons instead of conventional LDV seed particles, such as very small water droplets or polystyrene latex (PSL) particles. This paper discusses the development of a theoretical phase Doppler response model for stratified spheres, a dynamic response model to describe particle behavior in fluid-flows, the experimental facility, and the theoretical and experiment results.
