Beschreibung
Multiphase flows, the simultaneous flow of two or more physically distinct and immiscible substances, can be widely found in several engineering applications and determine very often safety and efficiency aspects of processes and plants where they occur. The measurement and imaging of multiphase flows has received much attention in recent years, largely driven by a need of many industry branches to accurately quantify, predict and control the flow of multiphase mixtures. In this volume of the book series "Dresden Contributions to Sensor Technology", the use of electrical impedance techniques for multiphase flow measurement has been investigated. Three different impedance sensor systems to quantify and monitor multiphase flows have been developed, implemented and metrologically evaluated. All sensors present high-speed capability and two of them allow for imaging phase fraction distributions. The sensors are furthermore very robust and can thus easily be employed in a number of multiphase flow applications in research and industry.
