Research Abstract

The ultimate goal of this research is to break a new ground of nonlinear nonequilibrium fluid mechanics by a comprehensive integration of molecular dynamics at the vapor-liquid interface and molecular gas dynamics based on the theory of Boltzmann equation. To this end, we have performed several specific analyses: 1. General formulation of nonequilibrium unsteady vapor motions accompanied with evaporation or condensation at the interface; 2. Establishment of reciprocity among elemental relaxation and driven-flow problems for a rarefied gas; 3. Careful investigation of applicability of macroscopic fluid mechanics to some nano-scale flows.
