Peter Dyson & Rajesh Ransing 
Fluid Properties at Nano/Meso Scale 
A Numerical Treatment

Today’s scientific and engineering community has a good grasp
on how to model fluid flows at macro and molecular scales, with
well-developed theory and supporting technologies. Between these
two extremes lies the nano/meso scale (i.e. in the range of
50nm-500nm) where fluid flow models continue to be problematic.
Continuum models used at macro scales assume a negligible influence
from molecular interactions, while molecular models do not predict
flow well at nano/meso dimensions. The solution, and the subject of
this book, is to use elements from both to capture correctly the
proper physics (from the molecular scale) and provide a description
in terms of useful fluid properties (as characterized on the
continuum scale).

Fluid Properties at Nano/Meso Scale is based on the
authors‘ past five years‘ research that has yielded new
innovations in fluid simulation strategies at the nano/meso scale.
The authors approach this subject in a straightforward and easy to
understand format, providing a first step into the subject for
researchers at all levels. They present new tools that allow the
numerical computation of fluid properties from first principles,
enabling the reader to begin to model successfully fluids at
nano/meso scale. It is hoped that these first steps will engender
the further development and advancement of simulation techniques at
this scale, and keep engineering simulation at the cutting edge of
technology.

Dr Peter Dyson, School of Engineering, Swansea University, Swansea
Peter Dyson gained his Ph D from the University of Swansea. His thesis ‚Numerical Computation of Fluid Properties at Nano IMeso, has opened up new areas in meso scale fluid simulation allowing the investigation of flow regimes and the characterization of bulk fluid properties from first principles. An EPSRC proposal to extend this work had been submitted and is currently under review.

Dr Rajesh Ransing, Senior Lecturer, School of Engineering, Swansea University, Swansea
Dr Ransing is an executive committee member, of the Natural Computing Applications Forum (NCAF). He is an Editorial Board Member of International Joumal of Numerical Methods for Heat and Fluid Flow Journal and has had numerous guest editor roles and awards for papers. He is an organizer of many conference workshops, and has been asked to be a guest speaker at many conferences also. His research with NCAF has resulted in global patents, which are being accepted in many countries. The University has created a spin out company to exploit this research and UK’s only Casting Trade Association – Cast Metal Federation along with other consortium members is actively supporting this research initiative.
