Samenvatting

Various aspects of boiling bubble deformation and oscillation have been examined or re-examined with an EulerLagrange approach. Anisotropic bubble deformation is easily converted into the acoustically powerful isotropic breathing mode. The structure of the added mass matrix involved explains this conversion. With a perturbation analysis, resonance cases in which this conversion is amplified or in which several different bubble sizes at a time are excited have been identified. The effects of finite disturbance amplitude and the proximity of the wall on oscillation frequency have been quantified. Experimental validation is reported of frequency reduction by the presence of the wall or by fixation of the bubble foot to a wall.
