This paper deals with a numerical investigation on sliding door and people moving effects on the indoor climate of a standard ISO5 class OT with an ultraclean air filter system and a total ceiling unidirectional diffuser. A simple method to analyze the effects on the OT climate by ... 詳細を見る

The increasing energy demand calls for advances in technology which translate into more accurate and complex simulations of physical problems. Understanding the rock damage is essential to understanding the geomechanics of hydrocarbon reservoirs. The fragile microstructure of some ... 詳細を見る

In this paper we present a transient numerical model of the heat transfer and thermochemical damage evolution in an IR translucent material using COMSOL Multiphysics. The model is evaluated using literature supplied and experimentally determined material properties for carbon black laden ... 詳細を見る

Solar radiation is a prominent contributor of energy in buildings, and can be transmitted directly into a building through opaque surfaces, but it can also be absorbed by building components (i.e. walls, roofs etc.). This study discusses the use and effect of ventilated facades, with an ... 詳細を見る

Introduction: Power electronic converters such as those for High Energy Physics Experiments (HEPEs) must operate in thermally hostile environment. Heat generated by electronics components must be conveniently dissipated to ensure electrical performances and improve reliability. Due to ... 詳細を見る

This paper presents the modeling and simulation results of wind velocities in urban areas. The main idea was to build random generated urban areas for studying the influence of different urban geometries, from relative open to more dense, on wind profiles. The Spalert-Allmaras turbulent ... 詳細を見る

Polymer gels belong to the realm of soft active materials as they are capable of responding to a non-mechanical stimulus – the permeation of a solvent – with a mechanical action – a volume change, thanks to the coupling between different physics. This mechanism of coupling can be ... 詳細を見る

Introduction: This work presents the design of a novel flow cell based miniaturized electrochemical respirometer to monitor organic content in water samples semi-continuously, in contrast to current Biochemical Oxygen Demand, BOD, methods. Simulation techniques has been used to ... 詳細を見る

Thermally conducting but electrically insulating materials are needed for heat-sink LED lighting applications. We report on a cost effective and innovative method based on creating core-shell nanoparticles in polymer with aluminum (Al) nanoparticles as the high thermal conductivity core ... 詳細を見る

We applied the Hot Wire (HW) technique and COMSOL Multiphysics software to study the heat transfer of a homogeneous and isotropic solid material. The HW technique is based on the application of a linear power density modulated by a rectangular pulse of heat, in a specific time period. ... 詳細を見る
