Visualization of Horizontal Settling Slurry Flow Using Electrical Resistance Tomography

Abstract

Settling slurry flow is very common and important in many industries, especially in slurry transportation, which need be monitored in practical operation. An investigation on visualisation of horizontal settling slurry flow in pipeline using electrical resistance tomography is reported in this paper. The internal images of fluid structure were displayed to operators by measuring the solids concentration distribution and solids velocity distribution in the pipe cross-section. Experimental investigation with 5% solids loading concentration at various transport velocities were conducted. Results obtained from electrical resistance tomography were compared with the results of photography and other flow measurement methods.
