Evaporative Processess and Vapor Nucleation via Molecular Simulations and Theory

Abstract

The PI will perform the following tasks:1) Determine mass and momentum accommodation coefficients for water and R134-a coolant using molecular dynamcis simulations.2) Perform a series of evaporation-condensation simulations in the simple heat pipe geometry to determine the limits of the evaporative cooling processes and to provide reference to the nucleation and bubble evolution simulations that involve evaporation/condensation processes.3a) Employ non-equilibrium simulations of liquids in the presence of heated solids", involving either ideal surface, or surface defects, such as groves or pockets of pre-existing gases, to directly observe vapor nuc"leation.3b) Characterize nucleation free energy barriers using advanced sampling techniques in equilibrium simulations.
