Optical fiber probes for particle size/velocity measurements: a simulation model. Part 2

The ray tracing model developed previously was used to simulate the performance of an optical fiber-based sensor system for the measurement of particle size and velocity in two-phase flows. Results indicated that both the visibility and phase lag measurement techniques are sensitive to the particle's shape and its trajectory through the measurement volume, particularly as the transmitting and sensing optics' distance from the measurement volume decreases. The model was also shown to simulate the behavior of an existing probe quite accurately.
