Fig. 2. Ratio of water volume to vessel volume as a function of time in the refilling vessel (A). Simulations are for three different vessel radii (r), and for a radius of 15 µm assuming a pure water vapour bubble and either allowing, or not, for the diffusion of air into the vessel. Other parameter values correspond to the base case (see Table 1). B, Pressure in refilling vessels with three different radii. Other parameter values correspond to the base case. Note that the hydrostatic pressure of free water at atmospheric pressure is set at 0·1 MPa, not at 0·0 MPa as used conventionally.
