Abstract
A novel optical technique has been developed to measure particle diameters in multiphase flows with high accuracy. This technique uses a photodiode array to measure the spatial frequency of the laser light scattering from a spherical particle located in the measurement volume. An optimized optical orientation angle is introduced by taking two scattering mechanisms into consideration, which provides high accuracy and avoids the measurement-volume effect in sizing large particles. The performance of the new method was simulated by using the generalized Lorenz-Mie theory (GLMT) and validated by experiments. The results show only 2% measurement uncertainty for particle sizes as large as 1200 ?m, which are commonly encountered in gas-solid and bubblywater multiphase flows. The feasibility of this technique was demonstrated experimentally.
