Stochastic Models of Thermodiffusion
New stochastic models of thermodiffusion are constructed and their hydrodynamical limits are studied through a first order Chapman-Enskog expansion. These models differ from earlier ones by taking into account all first order contributions proportional to the temperature gradient and, thus, allow for both positive and negative Soret coefficients, in accordance with observations.
متن کاملDie Selektivitätsabschätzung im Rahmen der Anfrageoptimierung im HEAD-System
Da im HEAD-System eine statische Anfrageoptimierung eingesetzt wird, ist die Größe der Zwischenergebnisdatenmengen zur Laufzeit nicht bekannt, so daß eine Abschätzung auf der Basis von Datenbankstatistiken erfolgen muß. Um eine Kostenbewertung vornehmen zu können, müssen daher entsprechende Statistiken vorliegen, insbesondere hinsichtlich der Kardinalität (Tupelanzahl) der einzelnen Relationen,...
متن کاملA Stochastic Approach to Thermodiffusion
In presence of thermal inhomogeneities, particle diffusion is known to occur even without concentration gradients. This phenomenon, known as “thermodiffusion” or “Ludwig-Soret effect” is well documented since the nineteenth century, and has numerous current applications which range from astrophysics to polymer physics and chemistry. In this contribution, we propose new microscopic stochastic mo...
متن کاملThermodiffusion in the Critical Region
Long range fluctuations of the order parameter affect thermodynamic as well as transport properties in the critical region. The values of transport coefficients near a critical point are typically enhanced compared to the values in the classical region far away from a critical point. Asymptotically close to a critical point, the critical enhancements obey power laws with universal critical expo...
متن کاملThermodiffusion of charged colloids: single-particle diffusion.
An expression for the single-particle thermal diffusion coefficient of a charged colloidal sphere is derived on the basis of force balance on the Brownian time scale in combination with thermodynamics. It is shown that the single-particle thermal diffusion coefficient is related to the temperature dependence of the reversible work necessary to build the colloidal particle, including the core, t...
