[en] The case of a spherical vapor bubble growing in an infinite, uniformly heated liquid, has been analyzed under the thin boundary layer approximation for the effects of a variable pressure effects can be quite important and dominate the rate of growth. For the case where pressure changes cause the vapor temperature to behave as t/sup n/, (t being time), the bubble radius will grow as t/sup n+1/2/, significantly faster than the √t behavior usually expected. The analysis has been shown to compare favourably with existing data
