Parabolic homogenization

WebNov 21, 2015 · In mathematical analysis, homogenization can be defined as a theory for replacing a PDE with rapidly oscillating coefficients by a PDE with averaged coefficients (an effective PDE) that describes the macroscopic behavior of the original equation. WebOct 17, 2024 · Microchannels offer unique advantages on heat transfer performance. In this paper, microchannels are applied to the compound parabolic concentrator (CPC) system. A multi-physical field coupling model based on Finite Element Method is proposed to investigate the homogenization effect of the microchannel heat absorber on the CPC non …

WebMay 1, 2011 · Abstract. We study the multiscale homogenization of a nonlinear hyperbolic equation in a periodic setting. We obtain an accurate homogenization result. We also show that as the nonlinear term depends on the microscopic time variable, the global homogenized problem thus obtained is a system consisting of two hyperbolic equations. WebThis paper addresses the issue of the homogenization of linear divergence form parabolic operators in situations where no ergodicity and no scale separation in time or space are available. Namely, we consider divergence form linear parabolic operators in Ω ⊂ R n with L ∞ ( Ω × ( 0, T)) -coefficients.
