1712 Fundamental study of multiple measurement system using ultrasound, electrical conduction and image processing for two-phase flow measurement(2)

Abstract

To measure the main parameter of the gas-liquid two-phase flow at the same time, the compound measurement system was developed. The compound measurement system is composed of Ultrasonic Time-Domain Correlation method (UTDC), Wire Mesh Tomography (WMT), and Digital Image Processing (DIP). UTDC and high-speed camera were introduced for a more detailed measurement of the gas-liquid two-phase flow. As a result, the monitor of the gas-liquid two-phase flow became possible. The bubbly flow adapts the compound measurement system in this research. Furthermore, the each parameter effects for bubbly flow structures are clarified using the compound measurement system.
