Study of flow properties of wet solids using laser induced photochemical anemometry. Final report

摘要

We have developed the LIPA (Laser Induced Photochemical Anemometry) technique for use in wet-solids and studied model mixtures. Refractive index matched, high Reynolds number (turbulent) solid-liquid flows, composed of silica particle (35-74 mu m diameter) in an aqueous solution, were used to enable LIPA measurements of highly loaded wet-solids in a vertical pipe setup. This non-intrusive technique involves use of photoexcitable chemicals, which upon excitation marked the solid-liquid mixture.
