چکیده

A method for numerical calculation of the eeective conductivity of a periodic array of cells is presented. Knowledge of bases for the space of solutions to the electrostatic equation in a cell is assumed. The method involves projection of the electric potential on these bases. Applications are made on two-dimensional two-phase tilings where polygons meet in bow-tie shaped corners and the conductivity ratio between the phases is high. Examples of numerical accuracy are given.

Two-color Fractal Tilings

A variety of two-color fractal tilings (f-tilings) are described, in which no two adjacent tiles have the same color. Two-colorable examples from f-tilings that have been described previously are identified, and two techniques are used for converting f-tilings that are not two-colorable into new f-tilings that can be so colored. In the first of these, tiles are combined in order to change the v...

اثرات بس ذره‌ای در مایعات الکترونی ابعاد کم

 This review article is about the role of electron-electron interactions in low dimensional systems and its transport properties in nano-structures. It begins with a review of the pair-distribution function theory of electron liquid systems taking into account the electron-electron interactions. We extend the theory for highly correlated system such two- and one-dimensional electron liquids. We...

سنتز گرافن سه بعدی و بهینه‌سازی مورفولوژی آن

Due to electrical properties (high electron mobility) and electrochemical characteristics (high electron transport rate), graphene-based  materials have been widely applied for various scientific fields. However, due to their two-dimensional  structures, these materials have low active sites for reaction. Therefore, changing from two-dimensional sheets dimensional to the three-dimensi...

Mixed Convection of Variable Properties Al2O3-EG-Water Nanofluid in a Two-Dimensional Lid-Driven Enclosure

In this paper, mixed convection of Al2O3-EG-Water nanofluid in a square lid-driven enclosure is investigated numerically. The focus of this study is on the effects of variable thermophysical properties of the nanofluid on the heat transfer characteristics. The top moving and the bottom stationary horizontal walls are insulated, while the vertical walls are kept at different constant temperature...

Transport Property Estimation of Non-Uniform Porous Media

In this work a glass micromodel which its grains and pores are non-uniform in size, shape and distribution is considered as porous medium. A two-dimensional random network model of micromodel with non-uniform pores has been constructed. The non-uniformity of porous model is achieved by assigning parametric distribution functions to pores throat and pores length, which was measured using ima...
