Computer Simulation of Equidxed Eutectic Solidifiction of Metals

In the present work, the solidification process was simulated in both macroscopic and microscopic scales. Two-dimensional heat transfer equation for conduction was applied for macroscopic modeling using enthalpy formulation and finite element method. In order to decrease execution time and/or memory capacity in finite analysis, skyline mathematical technique was adapted. The microenthalpy metho...

CANv2: A Hybrid CA Model by Micro and Macro-dynamics Examples

Cellular Automata (CA), one of the most challenging computational paradigms in microscopic and macroscopic complex systems simulation, can be successfully addressed also by using a modified CA classical approach. In this contribution we discuss related aspects in applying the CANv2 approach in examples of micro and macro dynamics such as: superconductive devices and forest fire simulation. Adva...

Solvent Effects on Tautomeric and Microscopic Protonation Constants of Glycine in Different Aqueous Solutions of 1,4-Dioxane

The acid-base equilibria of glycine have been studied in different aqueous solutions of 1,4-dioxane(0-50 % by v/v) using potentiometric method. In this study, the macro and micro protonationconstants of the amino acid and its tautomeric constant have been determined at 25 °C and constantionic strength 0.1 mol dm-3 (NaCl). The protonation and the tautomeric constants of glycine indifferent binar...

On Some Pdf Based Moment Closure Approximations of Micro-macro Models for Viscoelastic Polymeric Fluids

In this paper we will discuss several issues related to the moment-closure approximation of multiscale models for viscoelastic polymeric fluids. These moment-closure approaches are based on special ansatz for the probability density function (PDF) in the finite extensible nonlinear elastic (FENE) dumbbell micro-macro models which consists of the coupled incompressible Navier-Stokes equations an...
