Morphological stability of the interface of a bubble growing in a fluid. Two-dimensional case

The problem of two-dimensional round gas bubble growth in a fluid under the non-stationary inertial approximation is considered. We perform a linear morphological stability analysis. The harmonic perturbations near the bubble surface is studied by analytically and numerically. The morphological instability of the interface under infinitesimal perturbations is found and analyzed.
