Extractions: After completing his secondary schooling, David Enskog entered Uppsala University. He continued to study there for his doctorate after taking his first degree. In 1917 he was awarded his Ph.D. and then he spent several years teaching in secondary schools and colleges. In 1930 Enskog was appointed professor of mathematics and mechanics at the Royal Institute of Technology in Stockholm. Enskog worked on the Maxwell Boltzmann equations. These had first been formulated by Maxwell in 1867 to describe the flow of molecules, momentum and energy of a gas. This was reformulated by Boltzmann in 1872 in terms of a velocity distribution function. Enskog began to work on this equation for his master's degree at Uppsala and made a remarkable prediction. If a mixture of two gases is subjected to a temperature difference, the gas with the larger molecules concentrates at the lower temperature. A simple theory does not predict this behaviour. However Enskog predicted it in a paper written in 1911. In 1917 Chapman independently predicted it, but their theory was questioned until

Transition Regimes For Linear Kinetic Equations By David Levermore david Levermore Department of Mathematics University of Arizona Traditionally momentclosures or Chapmanenskog type expansions have been used to derive such http://www.ima.umn.edu/reactive/abstract/levermore2.html
Extractions: University of Arizona This talk presents a framework for deriving well-posed transition regime models. Traditionally moment closures or Chapman-Enskog type expansions have been used to derive such models. Moment closures lead to large first-order systems while expansions yield a single higher order equation that can be ill-posed. Elements of both these traditional approaches are present in the new framework, which yields well-posed systems of moderate size and order that capture the same formal accuracy as both larger moment systems and higher order Chapman-Enskog approximations.
Extractions: Technology is increasingly advancing into regimes in which particle mean-free paths are comparable to the length scales of interest, and where traditional transport models therefore break down. For example, drift-diffusion models of electron-hole transport break down for submicron semiconductors because the scale of interest are very small, while Navier-Stokes approximations of fluid dynamics break down in outer planetary atmospheres or space shuttle reentry problem, where the mean free path are very large. Such situations can be described by particle simulations but the cost of carrying these out is much greater than that of small mean-free path models, often becoming prohibitive when one is near small mean-free path regimes. This makes the simulation of problems in which transition regimes coexist with small mean-free path regimes particularly difficult. This difficulty is compounded when the geometry is complicated or even random.
