Solid-Liquid Two-Phase Flow Image Reconstruction in Microchannel Based on Tikhonov Regularization Method

Abstract:

Electrical resistance tomography (ERT) has been used as an alternative technique to monitor two-phase flow because of its high temporal resolution for monitoring fast transient processes. However the image reconstruction image with ERT in microchannel suffers from poor quality because of the interference of contact resistance. This paper aims at the solid-liquid two phase flow visualization in the cross-sections of a novel microchannel based on the ERT technique. Preliminary experimental results reveal that ERT image reconstruction technique base on Agilent data acquisition system can effectively detect the particle distribution in the microchannel.
