ABSTRACT

In this article, the Particle Image Velocimetry (PIV) technique was used in order to determine the velocity field of the ascending bubbles driven flow patterns in a glass being poured with champagne. Bubble nucleation and rise was induced at the bottom of the glass, on its axis of symmetry, from a ring-shaped etching done with adjoining laser beam points of impact. Both the velocity and vorticity fields were found to be in good agreement with previous qualitative flow visualizations as determined by means of laser tomography.
