Transport properties and structure of fluids in hydrophobic/hydrophilic nanochannels

摘要: When downsizing towards the nanoscale, system dimensions have been found to affect channel flows mainly because of presence walls that interact strongly with fluid particles. Parameters which are not taken into account at classical theory continuum macroscale, should be nano or even micro-scale where surface volume ratio increases significantly. Such property is wall/fluid interaction determines wetting (hydrophilic behavior) (hydrophobic a surface. We first investigate effect on atom distribution near wall through radial function and, next, we calculate three most important transport properties, i.e., diffusion coefficient, shear viscosity and thermal conductivity. Transport properties seem affected significantly in region adjacent wall.
