Entropy production estimate for the ES-BGK model with the correct Prandtl number
نویسندگان
چکیده
In this paper, we establish the entropy-entropy production estimate for ES-BGK model, a generalized version of BGK model Boltzmann equation introduced better approximation in Navier-Stokes limit. Our result improves previous entropy [38] that (1) full range Prandtl parameters −1/2≤ν<1 including critical case ν=−1/2 is covered, and (2) sharper bound obtained. An explicit characterization coefficient also presented.

abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...
15 صفحه اولAn Asymptotic Preserving Scheme for the ES-BGK Model of the Boltzmann Equation
In this paper, we study a time discrete scheme for the initial value problem of the ES-BGK kinetic equation. Numerically solving these equations are challenging due to the nonlinear stiff collision (source) terms induced by small mean free or relaxation time. We study an implicit-explicit (IMEX) time discretization in which the convection is explicit while the relaxation term is implicit to ove...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
