This paper presents the quantification of submerged gases using ultrasonic and optical techniques, comparing and analyzing the results obtained from the two methods, considering factors such as image processing and the size and rate of bubbles.
The quantification of submerged gas leaks can be performed by different techniques, using cameras, sonar or chemical sensors. This paper presents the quantification of submerged gases using ultrasonic and optical techniques. In the optical approach, a high-speed camera is used, and the captured images are processed using segmentation techniques. The segmented bubble is approximated by an ellipsoid and the largest projected diameter is determined. In this approach, partial overlap is also considered in the processing. In the ultrasound approach, a linear multi-element transducer is used to capture the images. In both methods the vertical velocity, bubble size, bubble emission rate, and leakage rate are calculated. The results obtained using the two methods are compared and analyzed.
