MODELING OF MICROSCALE TRANSPORT IN MULTIPHASE SYSTEMS
Abstract
This paper presents a summary of recent developments in
efforts to accurately microscale transport phenomena in
multiphase systems. In many such circumstances, the
transport is not accurately modeled by classical continuum
transport models. When this is true, alternative modeling
strategies such as molecular dynamic simulations, Monte
Carlo molecular simulation methods and analytical models
based on kinetic theory are often the most useful avenues of
analysis. This review paper focuses on such alternate
strategies. With the rapid increase of accessible computing
power in the past two decades, the capability of molecular
simulation methods to model microscale transport
phenomena in multiphase systems has increased
dramatically. Molecular simulation methods used to model
microscale aspects of phase equilibria in multiphase
systems, interfacial transport, melting and freezing
processes, growth and shrinkage of microdroplets by
evaporation and condensation, and high flux condensation
processes are discussed in detail. Prospects for future
development of these methodologies are also assessed.
Analysis schemes based on modified continuum theory and
non-equilibrium kinetic theory are also examined.
