Wire mesh tomography system for horizontal two-phase fluid flow investigation

Abstract

Simultaneous flow of liquid and gas is commonly found in process industries, such as petroleum pipeline transport, chemical process, oil and gas pipeline transport and many more. Phase distribution monitoring and visualizing for such flow is important to ensure the operation safeness and effectiveness. This study aims to investigate wire-mesh tomography system on solid-free two-phase flow monitoring and visualization. Experiment was conducted on a horizontal liquid/gas flow with an inner diameter of 84mm. A 16 x 16 wire-mesh sensor was designed and applied in this study to obtained the raw data from the target flow. The sensor worked together with transceiver circuit and data acquisition and image reconstruction software to visualize the flow condition and void fraction. Tomogram images were resulted as the final results of this experiment.
