Effect of Particle Statistics on Measurements of Transient Sprays by Single-Particle Counters,
Abstract
The effect of the single-particle limitation on the response of phase-Doppler instruments is determined for particle distributions which are spatially nonuniform and time-dependent. Poisson statistics are applied to particle positions and arrival times within the phase-Doppler probe volume to determine the probability that a particle is accepted. The results are then applied to a numerical simulation of a diesel spray. The calculated hypothetical response of the instrument provides a quantitative demonstration of the regimes within which measurements can accurately be made in such sprays. (Author)
