TITLE:	SMALL SCALE GASEOUS HYDRODYNAMICS: 
	GOING BEYOND NAVIER-STOKES

ABSTRACT: 

Small scale gaseous hydrodynamics has received significant attention both
in connection to microscale technology and due to the scientific challenges
it poses. In this talk we focus on the latter, and in particular the failure of the 
Navier-Stokes description when the characteristic system scale approaches 
the mean free path size. We will discuss both flow modeling and molecular 
simulation method development. On the flow modeling front, we will present
analytical and computational results on internal flows where the Navier-Stokes 
description cannot be applied. On the simulation methods development front, 
we will discuss recent work on molecular simulation error characterization 
(systematic and statistical) and development of efficient hybrid atomistic-continuum 
techniques.
