A cavity can support a gas-liquid interface with both positive and negative radius of curvature.
Definition of parameters in a generic cavity.
Geometry of the four cavities.
The evolution of the gas pocket in the four different cavity types: (a) conical crevice, (b) cylindrical cavity, (c) elliptical crevice, and (d) spherical cavity.
Evolution for the gas pocket in the four different types of cavity, when the interface initially starts half-way up the cavity: (a) conical crevice, (b) cylindrical cavity, (c) elliptical crevice, and (d) spherical cavity.
Variation in the threshold with the initial starting height of the interface within the cavity for (a) the conical crevice, (b) the cylindrical cavity, and (c) the elliptical crevice. The result for the spherical cavity is very close to (b) (not shown).
Evolution of a gas pocket during the second and third phases, where the mass of gas in the pocket at the start of the second phase is a proportion of the original mass, for (a) conical crevice, and (b) spherical cavity.
Geometric parameters used for the four cavities.
