Research ArticleOpen accessIn the abstractAnalysis of Heat Transport in a Proton Exchange Membrane (PEM) Fuel CellE. Afshari, S.A. JazayeriIn this study a two-phases, single-domain and non-isothermal model of a Proton Exchange Membrane (PEM) fuel cell has been studied to investigate thermal management effects on fuel cell performance. A set of governing equations, conservation of mass, momentum, species, energy and charge for gas diffusion layers, catalyst layers and the membrane regions are considered. These equations are solved numerically in … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,342 accessesView PDFCite
Research ArticleOpen accessIn the abstractThree Dimensional Hydrodynamic Model With Multiquadtree MeshesGregorio Posada Vanegas, Rodolfo Silva Casarín, Sébastien de BryeThis study presents a three dimensional model for the transport of conservative contaminants, which can be used for bodies of water which are affected by winds and/or tides. The model solves the equation of mass transport, based on results obtained using a hydrodynamic model for shallow waters that works in a finite volume scheme and a type of hierarchical grid, … …American Journal of Environmental Sciences, Vol. 4, Issue 3 · 30 Jun 2008 · 6,578 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of Cross and Single Sided Naturally Ventilated Rooms Using CFDK. Visagavel, P. S.S. SrinivasanNatural ventilation contributes to the improvement of thermal comfort and quality conditions of the internal air, while at the same time it is recognized as a very efficient technique that, when applied properly. The present project refers to the numerical prediction of air velocities in cross and single-sided naturally ventilated rooms, which are considered along with atmospheric zone. Continuity and … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 6,738 accessesView PDFCite
InvestigationOpen accessIn the abstractSimulation and Experimental Analysis of a Demonstrative Solar Heating and Cooling Plant Installed in Naples (Italy)Annamaria Buonomano, Francesco Calise, Massimo Dentice d'Accadia et al.In this study the model of a Solar Heating and Cooling (SHC) system and its experimental setup are presented. The SHC system under investigation is a demonstration plant installed in Naples, based on flat plate solar collectors and a single-stage LiBr-H2O absorption chiller. In addition, two vertical tanks are installed as storage system. The balance of system includes: A cooling … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 10 Oct 2016 · 7,802 accessesView PDFCite
