Using large scale molecular dynamics (MD) simulation techniques, two types
of fluid-fluid phase changes were investigated. One is a homogeneous nuclea
tion process from supersaturated vapor, in which we compare a Lennard-Jones
system and water system. Another is a bubble formation (cavitation) proces
s in stretched liquid, in which we compare one-component and two-component
systems. (C) 1999 Elsevier Science B.V. All rights reserved.
