This paper is about the influence of the diffusion coefficient when simulating mixed electrode materials. The results show that when simulating dynamic behavior of a lithium ion battery cell with mixed electrode material the diffusion coefficients is very important. En savoir plus

We theoretically simulate the antireflective effects of oxide nanosphere monolayer films in the visible spectrum. The essential geometric and material parameters of nanosphere films are simulated and different functions are proposed to describe the dependence of reflectance on the ... En savoir plus

In the framework of the Austrian FFG project SaLüΗ!, a compact mechanical ventilation system with integrated micro-heat pump was developed. The aim was a high level of prefabrication and a compact design allowing for installation also in small flats, e.g. into the façade. Due to the ... En savoir plus

Multi-physics simulations of the evolution of cure induced stresses in a viscoelastic thermoset polymeric resin are presented. The viscoelastic material model is implemented with a relaxation spectrum with 34 relaxation time constants. The trends in viscoelastic stresses at different ... En savoir plus

Some types of mechanical devices, such as molds, but not only, include a large number of micro-mechanisms, valves, channels, vents, or other devices subject to deterioration or malfunctioning, frequently caused by unwelcome phenomena such as incrustations, fillings, or reciprocal bonding ...

This poster presents a numerical modeling approach for hygrothermal behavior of bio-based materials. The mathematical model describes the heat and moisture transfer through a wall of bio-based materials. The studied wall is subjected to both convective heat transfer and moisture flux ...

Reducing HVAC energy consumption in buildings has provoked a lot of thought and has, subsequently, drawn a lot of attention. Out of the several methods that have been introduced to achieve this goal, the usage of Phase Change Materials (PCMs) in the structural components is one of the ... En savoir plus

Charged particle beam manipulation requires magnetic dipoles for steering and quadrupoles for focusing. Conventional magnets are currently used leading to very large and heavy systems. Miniaturization of the optic magnets would enable the development of more affordable systems and ... En savoir plus

A numerical multiphase flow model is proposed to predict the behavior and motion of entrained inclusions in liquid steel, as they enter the orifice of a LiMCA (Liquid Metal Cleanliness Analyzer) sensor for assuring steel quality. The method of measurement is based on the electric sensing ... En savoir plus

Introduction: The simulation of coupled heat and moisture transfer in constructions is becoming even more important in the last years. COMSOL Multiphysics represents a powerful tool for this kind of simulations as shown in [1,2,3], although applications in this area are still rare. For ... En savoir plus
