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, ...

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 ...

Impact of human activities on the climate is evident, and the recent anthropogenic production and discharge of greenhouse gases into the atmosphere is highest in history. The current climate change have had worldwide influence on human and natural systems for example; global warming, melting of ice and snow, and rise in sea level etc. (AGECC 2010, Council 2013, IPCC, 2014). Increase in 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 ...

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 ...

Standing column wells (SCW) are open-loop geoexchange systems used to provide space heating and cooling to buildings. As they use groundwater as heat carrier fluid and modify its thermo-chemical conditions along the year, they may favor calcite dissolution and precipitation, thus increasing maintenance costs. In order to predict the thermo-hydro-chemical (THC) processes occurring in a SCW and ...
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 ...

Fluid injection in deep wells is a basic procedure in geothermal permeability enhancement. The retrieved changes of Pressure and Temperature are subsequently considered as sources of incremental stress and strain changes, using the elastic model from COMSOL Multiphysics®, which are then converted to Coulomb stress changes on favoured faults, taking into account also the background regional ...

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 ...
