Kinetic Boundary Layers and Fluid-Kinetic Coupling in Semiconductors
نویسندگان
چکیده
The semiconductor Boltzmann equation with elastic collisions as the dominating scattering eeects is considered. For the corresponding uid limit, the spherical harmonics expansion model, kinetic boundary layers are analyzed and higher order accurate boundary conditions are constructed. In a further step, boundary value problems for the energy transport model and the drift-diiusion model are derived. As an application, interface conditions for the uid-kinetic coupling in a domain decomposition approach are presented.

It has been carried out during a visit of the second author at Univ.

Effects of coupling on turbulent gas-particle boundary layer flows at borderline volume fractions using kinetic theory
This study is concerned with the prediction of particles’ velocity in a dilute turbulent gas-solidboundary layer flow using a fully Eulerian two-fluid model. The closures required for equationsdescribing the particulate phase are derived from the kinetic theory of granular flows. Gas phaseturbulence is modeled by one-equation model and solid phase turbulence by MLH theory. Resultsof one-way and...
متن کاملThe high field asymptotics for degenerate semiconductors: Initial and boundary layer analysis
In a previous paper [Math. Meth. Mod. App. Sci, vol. 11, 1253-1272, 2001], the high field limit for degenerate semiconductors is analyzed by the authors. The scope of the present paper is the extention of this analysis to boundary value problems. The initial layer, modeled by a homogeneous Boltzmann equation with a frozen electric field provides an initial condition for the high field solution....
متن کاملLinear Kinetic Heat Transfer: Moment Equations, Boundary Conditions, and Knudsen layers
A linear kinetic equation for heat transfer is solved by means of the method of moments. The moment equations are solved with Maxwelltype boundary conditions for steady state energy transport. The results exhibit marked Knudsen boundary layers. The accuracy of the description is examined, and it is shown that already a relatively small number of moments can give satisfactory resolution of Knuds...
متن کاملFree vibrations analysis of a sandwich rectangular plate with electrorheological fluid core
In this paper, a rectangular sandwich plate with a constrained layer and an electrorheological (ER) fluid core is investigated. The rectangular plate is covered an ER fluid core and a constraining layer to improve the stability of the system. The two outer layers of the sandwich structure are elastic. The viscoelastic materials express the middle layer behavior under electric field and small st...
متن کاملAbout Boltzmann Equations for Transport Modeling in Semiconductors
We present some results on the mathematical analysis of kinetic equations for modelling transport processes in semiconductors. We focus our attention on the connection between the kinetic models and the fluids ones based on driftdiffusion or hydrodynamic equations. Asymptotic analysis gives hydrodynamic coefficients in, terms of microscopic quantities and allows to derive accurate boundary cond...
