Bubble Growth under Nonuniform Initial Conditions

Bubble Growth Under Nonuniform Initial Conditions 1. Introduction [Pg.20]

In actual practice vapor bubbles almost always originate at solid surfaces, rather than in the midst of a large body of uniformly superheated liquid. This introduces a number of additional complications, whose effect in most cases is still largely unknown. Even for isolated bubbles the spherical shape is [Pg.20]

Note that this is not a Lagrangian transformation, although the bubble wall is immobilized. The initial temperature function is taken to be a quadratic [Pg.22]

The bubble wall is assumed to be at the saturation temperature corresponding to the ambient pressure  [Pg.22]

New independent variables are now introduced into Eq. (63) s =y/R as a position variable, and jR(f) as a time variable, giving [Pg.22]
