In response to continued miniaturization and increased multi-functionality of electronic circuits, the number of integrated circuit (IC) packages on the circuit board continues to increase. As a consequence the operating power density increases and significant increases in the operating temperature of devices result. To maintain operation and long term performance device temperature must be ...

The poster presents a methodology to account for thermal effects on battery cells to improve the typical thermal performances in a pack through heating calculations generally performed under the operating condition assumption. The aim is to analyze the issues based on battery thermo-physical characteristics and their impact on the electrical state of battery cells(Khan, Mulder et al. 2013, Khan, ...

A Finite element model of plasma sprayed TBC’s was developed to estimate the stress induced by thermal cycling experiments. A heat transfer analysis was performed to evaluate the temperature distribution on the specimen during the cooling under an impinging air jet; temperature measurements performed with an infrared pyrometer on the cooled samples show good agreement with the evaluated ...

Our safety analysis group in the Research Reactors Division of Oak Ridge National Laboratory supports a project to investigate the production of Pu-238 isotope for missions of deep space travel in the High Flux Research Reactor. COMSOL Multiphysics® has been used to support this activity in the past, and we have successfully installed and irradiated three different target designs. The gas-gap ...
A COMSOL Multiphysics® Software Interface with GEMS3K for Modeling Reactive Transport (Geo)Chemical Processes

 Oregon State University, Corvallis, OR, USA
This paper presents a generic interface for reactive transport process modeling that was developed between the COMSOL Multiphysics® software Java API (transport model) and GEMS3K (reaction model). While the transport of different species, kinetics of dissolution/precipitation, system potentials, fluid and gas flow, etc. can be modeled in a complex chemical system with COMSOL® software, the ...

INTRODUCTION: This paper investigates the design of IPMSM as drive motor for an electric race car in the competition called Formula Student. A key parameter for electrical motor is the power density which is very important for the performance of such race vehicles  to keep the overall mass small at high power. Furthermore, to run the motor at high power and to prevent it from overheating due ...

This paper deals of a technology involved in the joining of thermoplastic composites, the resistance welding technology. This process takes advantage in the repeatable melting process for the thermoplastic resins. The process was numerically modeled to study the effect of the two main process parameters, the electric power density applied to the heating elements and the exposure time at the ...

An important part of the society considers an increased share of renewable energies as an integral part of a strategy towards a sustainable future. As far as heat supply is concerned, this can be achieved using solar thermal collectors, borehole heat exchangers or trough the combustion of biomass. This article shows two applications of two configurations of twisted conduit inside the external ...

High levels of Indoor Air Quality (IAQ) in Operating Theatres (OT) is an important issue in order to contribute in prevention of Surgical Site Infections (SSI). Despite of specific plant layouts are applied for OT ventilation (e.g. unidirectional flow), the effective use conditions can heavily modify the design microclimate and air quality levels. Medical staff presence and movements and sliding ...

A requirement of the building envelope is to act as environmental separator. Energy is one component that we sometimes wish to control. How can this yield passive benefits such as solar heating? This research focuses on control of thermal radiation energy, and the role windows play as transfer medium between indoor and outdoor environments. A novel concept for passively controlling solar ...
