Title: Condensation of a vapor bubble in submicrometer container
Abstract: Condensation of a spherically symmetric submicrometer size vapor bubble studied using diffuse interface hydrodynamic model supplemented by van der Waals equation of state with parameters characteristic for The bubble, surrounded by liquid, is held in a container of volume with temperature of the wall kept fixed. The is triggered by a sudden rise of the wall temperature. We that in the same container and subjected to a similar increase of wall temperature the condensation process is totally different from opposite process of droplet evaporation. In particular, the rapid of the wall temperature excites the wave, which hits the and compresses the bubble, leading to a considerable increase the temperature inside. The condensation of the submicrometer size takes tens of nanoseconds, whereas evaporation of the same size lasts roughly 50 times longer. In contrast to evaporation the process is hardly quasistationary. (c) 2005 American Institute of Physics.
