Abstract

The description for rising bubble is important for the study of principle of the Gas/liquid two-phase flow. As to the rising bubble, reconstruction the shape of the bubble can make a strong foundation for further description. The bubble images were collected with two cameras; the images were preprocessed using digital images processing methods; parameters of the simulated ellipse were extracted with Hough transformation; and bubble simulated ellipsoid model were reconstructed based on these extracted parameters.
