The use of ventilated facades may reduce the cooling and heating energy demands of the building. Double-skin facades (DSFs) belong to the wider group of ventilated facades and currently represent one of the most interesting and studied facade systems. The purpose of this study is to investigate the thermal behaviour and performance of a DSF being designed for a real project in the Middle East ...

In a modern IC design, the capability of predicting the temperature profile is critically important as well as cooling and related thermal problems are the principal challenges. To address these challenges, thermal analysis must be embedded within IC synthesis. This paper presents thermal analysis of the FCBGA chip with a 4mm×4mm×0.3mm silicon die. The silicon die dissipates heat flux of ...

In this work, a methodology is developed, based on the application of finite element method in the frequency domain, using the COMSOL Multiphyics software, aiming the sensibility analysis of inductance calculation involving some configurations of an E-core magnetic circuit. Such important analysis, are made from several geometries and considering different frequencies for the source current ...

This work investigates the possibility of thermal activation of future tunnels to heat and/or cool the surface buildings or infrastructure such as subways stations. The principle is to insert pipes in the tunnel lining segments, which are connected to a geothermal pump. A heat transfer fluid antifreeze circulates inside the tubes to exchange heat with the surrounding environment (tunnel air and ...

The Integration of contact heat measurement with intelligent fire fighter gloves assumes parametric simulations with the heat transfer module of COMSOL. A thermocouple is embedded into high temperature protective layers of the glove and measures contact heat. This is done by by pressing the hand backside of the glove against a hot device like a door. The Heat transfer module has been used to ...

Calibration of field instruments used in radiation treatment clinics is currently traceable to NIST primary standards via protocols involving static, flat-field radiation beams. By contrast, radiation beams prescribed for treating cancer incorporate temporal and spatial modulation strategies in order to maximize dose to the tumor while sparing healthy tissue. Differences in the detector ...

For combustion simulations, the wall temperature and heat transfer is an important piece of information. Coal combustion systems typically have walls that are initially a cast ceramic, but, with time, slag is deposited on the surface and coal and soot are incorporated into the slag. It is this slag coated ceramic that determines the rate at which heat is transferred from the wall combustion ...

A frequently occurring geometry for heat exchangers is that of a long tube wound into a helix or spiral around a core volume. There is to be heat exchange between the tube and the gases (or solids) in the core. However, the length scales of these two parts of the geometry are very different, thus complicating the interface between the tube and the core processes. Usually, the tube is too ...

Standard measuring techniques for thermal conductivity cannot be readily applied to determine the load-dependent thermal conductivity of porous adsorbents, because the local ad- and desorption inside the specimen and the thickness of the specimen are not considered. Hence, in this work a new measuring procedure combining the transient hot bridge (THB) with a three dimensional finite element ...

The four foot diameter class A evaporation pan is used by the scientific community as the standard for determining evaporation rates for a number of purposes. The COMSOL Multiphysics® software provides the necessary tools to adequately develop synthetic estimates of evaporation values for input into hydrologic simulation models and other earth science applications. This paper presents ...
