A Computational Framework for Modeling One-Dimensional, Sub-Grid Components and Phenomena in Multi-Dimensional Micro-Systems

Authors:M.Z. Pindera, S. Bayyuk, V. Upadhya and A.J. Przekwas
Affilation:CFD Research Corporation, U.S.A.
Pages:727 - 730
Keywords:filament, fiber, computational models, sub-grid models, reduced models
Abstract:This paper presents a framework for modeling essentially one-dimensional devices and components embedded in multi-dimensional spaces. The main characteristic and main advantage of the new methodology is that the one-dimensional and multi-dimensional objects or domains are meshed completely independently of each other, without regard to their relative alignment or location, and subsequently combined into a single, unified composite mesh. The coupling of the solution between the different domains is handled fully-automatically in the solver, entirely through exchange of source terms between these domains of differing dimensionality. The source terms are evaluated locally on a cell-by-cell basis, depending on the solution values in these domains and the manner in which the one-dimensional grids intersect the multi-dimensional grids. The capabilities and usefulness of the method are demonstrated with several examples.
