AbstractThis chapter introduces the measurement, visualization, and characterization of settling slurry flow using Electrical Resistance Tomography (ERT). It starts by presenting the physical mechanisms governing hydraulic transport of solid particles, along with the typical slurry flow patterns in a pipeline. It then explains the ability of ERT for characterization of solid–liquid flow through solids volume fraction measurement, solids axial velocity measurement, and solids flow visualization. By the end of the chapter, the ability of ERT and its utilization for estimation of some parameters related to stratified slurry flow, such as mean granular bed concentration, mean granular bed velocity, the height of granular bed, the height of shear layer and the height of turbulent zone at the upper part of the pipe, are fully discussed. The limitations of ERT in slurry flow measurement and visualization are also highlighted.
