Today's scientific and engineering community has a good graspon how to model fluid flows at macro and molecular scales, withwell-developed theory and supporting technologies. Between thesetwo extremes lies the nano/meso scale (i.e. in the range of50nm-500nm) where fluid flow models continue to be problematic.Continuum models used at macro scales assume a negligible influencefrom molecular interactions, while molecular models do not predictflow well at nano/meso dimensions. The solution, and the subject ofthis book, is to use elements from both to capture correctly theproper physics (from the molecular scale) and provide a descriptionin terms of useful fluid properties (as characterized on thecontinuum scale).
Fluid Properties at Nano/Meso Scale is based on theauthors' past five years' research that has yielded newinnovations in fluid simulation strategies at the nano/meso scale.The authors approach this subject in a straightforward and easy tounderstand format, providing a first step into the subject forresearchers at all levels. They present new tools that allow thenumerical computation of fluid properties from first principles,enabling the reader to begin to model successfully fluids atnano/meso scale. It is hoped that these first steps will engenderthe further development and advancement of simulation techniques atthis scale, and keep engineering simulation at the cutting edge oftechnology.
* Presents internationally leading developments in the field offluid properties at nano/meso scale
* Provides the reader with the first steps to fluid modelling atnano/meso-scales as well as state-of-the-art applications
* Includes innovative and new simulation techniques along with adetailed examination of existing numerical methods
