摘要

In this chapter, we report a new mode of heterogeneous cavitation, i.e. evaporation-induced cavitation in water-filled hydrophilic nanochannels under enormous negative pressures. The liquid menisci in nanochannels are observed to be pinned at the entrance while vapor bubbles form and expand inside during the evaporation. It is observed that the growth rate of the vapor bubbles is controlled by water evaporation at the channel entrance, which is actually significantly enhanced due to absence of vapor diffusion along the nanochannel. We also report previously unexplored bubble nucleation, growth, stability, translational symmetry and dynamics that seem to be unique at the nanoscale.
