VOLUME FLOW RATE MEASUREMENT IN VERTICAL OIL-IN-WATER PIPE FLOW USING ELECTRICAL IMPEDANCE TOMOGRAPHY AND A LOCAL PROBE

Volume Flow Rate Measurement in Vertical Oil-in-water Pipe Flow Using Electrical Impedance Tomography and a Local Probe

This paper presents the use of a high performance dual-plane electrical impedance tomography (EIT) system and a local dual-sensor conductance probe to measure the vertical upward co-current oil-in-water pipe flows. Experiments were carried on a flow loop with a transparent 2.5 m long, 80 mm inner diameter test section using kerosene and tap water. The flow conditions were predominantly of the d...

Flow Pattern and Oil Holdup Prediction in Vertical Oil–Water Two–Phase Flow Using Pressure Fluctuation Signal

In this work, the feasibility of flow pattern and oil hold up the prediction for vertical upward oil–water two–phase flow using pressure fluctuation signals was experimentally investigated. Water and diesel fuel were selected as immiscible liquids. Oil hold up was measured by Quick Closing Valve (QCV) technique, and five flow patterns were identified using high-speed photo...

A method for bubble volume measurement under constant flow conditions in gas–liquid two-phase flow

Measuring the volume of a bubble, especially at its detachment, is a basic subject in gas-liquid two-phase flow research. A new indirect method for this measurement under constant flow conditions is presented. An electronic device is designed and constructed based on laser beam intensity. This device calculates the frequency of the bubble formation by measuring the total time of the formation p...

Applications of Electrical Impedance Tomography in Neurology

Introduction: Electrical impedance tomography (EIT) is a non-invasive technique utilized in various medical applications, including brain imaging and other neurological diseases. Recognizing the physiological and anatomical characteristics of organs based on their electrical properties is one of the main applications of EIT, as each variety of tissue structure has its own electrical characteris...
