Solid-liquid two-phase flow image reconstruction based on ERT technique in microchannel

Monitoring the flow behaviour on the micro-scale is very important in many industrial and biochemical process, the multiphase coexistence in microchannel provides many attractive characteristics compared to a single-phase flow. The precise flow rate control and well-defined channel geometries make it possible for us to make detailed investigation on multiphase flow phenomena on micro scale. This paper aims at the solid-liquid two phase flow visualization in the cross-sections of a novel microchannel based on the electrical resistance tomography (ERT) technique. Experimental results reveal that ERT image reconstruction technique base on Agilent data acquisition system can effectively detect the particle distribution in the microchannel © 2013 Universitas Ahmad Dahlan.
