The energy pay back is one of the most interesting field especially in the steel industry where this contribution is strictly connected to steams and emissions inside and outside the plant. Perhaps, this application is sometimes disturbed by a strong variation of emissions (\"off gas\"). One example is the arc furnace where the process is very discontinuous and there are many fluctuations in the ...

A design method for BHE fields in the absence of groundwater flow is presented, based on the superposition of effects. The effects of any periodic heat load with a period of one year can be obtained by a weighted sum of the effects of a monthly unit step heat load, properly displaced in time. The interference among BHEs is evaluated by the superposition of effects in space. The result of the ...

In 2010 an estimated 109 million infants were immunized against DTP, which serves as a good proxy for vaccinations in general. At the same time, however, approximately 19.3 million infants worldwide were not reached by routine DTP immunization services. Immunization rates tend to be lowest in areas where poor infrastructure and limited access to electricity can cause vaccine stock-outs and ...

In this study, the basic catalyst layer (CL) structure, consisting of carbon-supported Pt particles (C|Pt) and an ionomer binder, is investigated numerically by using COMSOL. The significance of modeling discrete Pt particles on the carbon support is highlighted by comparing the cell performance results to the case in which the Pt is assumed to be distributed uniformly over the carbon support as ...

The Large Hadron Collider at CERN has begun operations at 7 TeV center of mass energy. CERN plans to run at this energy until the end of 2012 with the goal of providing an integrated luminosity of a few fb?¹ to the CMS and ATLAS experiments. The LHC will then shut down for 1.5 to 2 years to make the revisions necessary to run at ~14 TeV. Operation resumes in 2014. In 2017/18, there will be ...

Groundwater is a key factor affecting mine operations worldwide. On one hand, both underground and open pit mines need to pump out groundwater in order to proceed with mineral extraction and increase the stability of rock slopes. On the other hand, groundwater abstractions can produce undesired environmental and social impacts, which should be anticipated in the environmental impact assessments ...

Developments intended to improve system efficiency and reliability for water and carbon dioxide separation systems to be used on crewed vehicles combine sub-scale systems testing and multiphysics simulations. This paper describes the development of COMSOL Multiphysics® simulations in support of the Atmosphere Revitalization Recovery and Environmental Monitoring (ARREM) project within NASA's ...

Solid Oxide Fuel Cells (SOFC) and Li-ion batteries (LIB) are electrochemical devices where performance is dependent on reactions inside porous electrode microstructures. Here we use tomographic techniques to probe 3D electrode structures (anodes and cathodes) at micro-nanometer length scales. Subsequently, micro/nano structural changes in electrodes are characterized and quantified. Utilizing ...

In this work, we study the design of a new integrated system for Solar Water Heating that combines the solar thermal energy collection (primary circuit) with the heat storage (secondary circuit) into the same device. We have performed different finite element method simulations using COMSOL Multiphysics®, for solving the equations of heat transfer (conduction and convection) and those of fluid ...
