Multi-dimensional Electric Impedance Sensors for Multiphase Flow Investigations

Description

Multiphase flow research inevitably requires flow experiments commonly performed in small and medium scale test facilities. More and more, multi-dimensional and non- or minimal invasive measurement and sensors are needed to generate accurate data which in turn support (CFD) flow model development and validation. For this reason, in the past a number of sensors and instrumentation to monitor multiphase flow have been developed. Electrical impedance sensors, in which the measurand causes a variation of an electrical property such as resistance or capacitance, have been successfully applied for the measurement of flow parameters in multiphase mixtures. In this talk, an overview on selected impedance-based measurement techniques and sensors applied to the monitoring of multiphase pipe flows is given. Different sensors, instrumentation and data processing techniques are presented as well as some applications are shown. Hence, beginning with simple impedance probes up to tomographic (multi-electrode) sensors along with some current trends for the further development and optimization of this versatile measurement technique will be described and discussed.
