Abstract

A two-phase flow in a translucent cylinder pipeline was studied using high-speed video system. Series of images were taken for recording flowing information. An innovative bubble filling algorithm named infective algorithm was used to fill the center of edge closed bubble in the binary image. The modified infective algorithm was applied to the binary images with ringent bubbles in this paper, which make up for the disadvantage of the simple infective algorithm. The area and the geometric center of the bubble were acquired from the filled image. Then the track of bubble rising was acquired by the geometric center. Experimental results have shown that the bubble could be well tracked.
