An ascending bubble is deformed by fluid loads while surface tension drives it towards a spherical shape. In contrast to a priori prescribed constant shapes, coupling of the particle shape to the surrounding liquid is realized here in the framework of an immersed boundary method. A method is proposed where the bubble shape is modelled by an ellipsoid of variable aspect ratio or by spherical harmonics.
