Abstract

A ray tracing model was developed to simulate the performance of an optical fiber-based sensor system for the measurement of particle size and velocity in two-phase flows. The model describes how particle size and velocity measurements based on the visibility and phase lag techniques behave when the size of the transmitting and sensing optics, their proximity to the measurement volume, and the size of the measurement volume itself are comparable with or larger than the size of the particle being measured.
