Abstract
The objective of this paper is to develop a method for flow regime identification by using reflected ultrasonic intensity. This study applies ultrasonic signal and measures strength of the reflected signal from bubbles in bubbly flow, slug flow, annular flow and single-phase flow. This study is performed in an air-water circular pipe with a diameter of 50 mm. The total height of this apparatus is 7 m. The reflected ultrasonic intensity values from gas phase in wall-peak and core-peak bubbly flow, slug flow, annular flow and single-phase are obtained. Summation patterns of the normalized positive ultrasonic intensity of each repetition in 3 seconds of core-peak bubbly flow, wall-peak bubbly flow, slug flow, annular flow and single-phase flow in the three areas, the area at near the ultrasonic intensity probe, the area at the middle of pipe and the area at far from the ultrasonic intensity probe, are shown and discussed in this study.
