A stochastic geometrical 3D model for time evolution simulation of microstructures in SOC-electrodes

نویسندگان

چکیده

An original 3D stochastic geometrical model has been developed to simulate the microstructural evolution of porous solid-oxide cell electrodes made yttria-stabilized zirconia and nickel. The change induced by Ni agglomeration more specifically simulated. is based on random sets algorithms for solving linear assignment problem related time one component in microstructure. possibility generate realistic microstructures with verified comparing characteristics synthetic those extracted from real electrode reconstructions. ability Stochastic Time Evolution Microstructure (STEM) evolving then illustrated compared data obtained aged electrodes. error most are general lower than 10%, except some particular cases, such as microstructure factor. All results have discussed suggestions proposed improving model.

investigating 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...

a study on thermodynamic models for simulation of 1,3 butadiene purification columns

attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...

A new stochastic 3D seismic inversion using direct sequential simulation and co-simulation in a genetic algorithm framework

Stochastic seismic inversion is a family of inversion algorithms in which the inverse solution was carried out using geostatistical simulation. In this work, a new 3D stochastic seismic inversion was developed in the MATLAB programming software. The proposed inversion algorithm is an iterative procedure that uses the principle of cross-over genetic algorithms as the global optimization techniqu...
