Flow Measurement in Porous Media Using Particle Tracking Velocimetry and Matching Refractive Index
Abstract
In this study, an experiment in a packed bed column is performed to obtain pore-scale full-field velocity components of the flow. Particle tracking velocimetry (PTV) technique is used to obtain instantaneous accurate flow fields and detailed information of the flow patterns. A refractive index matching liquid is used to provide the required transparency, so the measurements could be performed at the middle plane of the packed bed reactor. Immersion optical methods are applied to explore transfer phenomena in multiphase granular beds. In this research, P-Cymene 99% is investigated as the working fluid in a packed bed vertical square channel for the immersed method. P-cymene is chosen because of the close similarity of its physical properties to those of the water.
