Research ArticleOpen accessAll words, across the recordTHE USE OF DIFFERENT LEVELS OF MULTI-ROOM MODELING APPROACH-APPLICATION TO BUILDING POLLUTION TRANSPORT AND EFFICIENCY OF OFF-HOUR VENTILATIONAhmed Cherif MegriSeveral building simulation programs have been developed for design, analysis and prediction of the distribution of temperature, airflow and heat transfer between inside and outside of a building and/or between different zones of the same building. These programs are categorized as mono-zone models, multi-room models, zonal models, Computational Fluid Dynamics (CFD) models and multi-zone models. The number of computer programs … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 25 Mar 2014 · 7,768 accessesView PDFCite

Venkatraman, G. DevaradjaneProblem statement: The present work describes a theoretical investigation concerning the performance of a four strokes compression ignition engine, which is powered by alternative fuels in the form of diesel and diesel biodiesel blends. Approach: The developed simulation model used to estimate the cylinder pressure, heat release rate, brake thermal efficiency, brake specific fuel consumption and engine out emissions. The … …American Journal of Applied Sciences, Vol. 8, Issue 9 · 2 Aug 2011 · 7,727 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordModeling of Nitric Oxide Formation in Single Cylinder Direct Injection Diesel Engine Using Diesel-Water EmulsionK. Kannan, M. UdayakumarProblem statement: Water injection into the combustion chamber of diesel engine found to be one of best method for in-cylinder control of NOx formation. Approach: The combustion of water-diesel emulsion in diesel engine was simulated using a computer program to estimate the heat release rate, cylinder pressure, brake thermal efficiency, brake specific fuel consumption and NO formation. Results: The numerical … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 7,268 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordGOSTE: Group Oriented Simulation Training EnvironmentKorichi Ahmed, Belattar BrahimThe purpose of this study is to explore the contribution of the CSCW (Computer Supported Cooperative Work) in the collaborative project conduct and more specifically in the conduct of a simulation training project. We justify the adequacy of the CSCW concepts with the method of conduct of a simulation project. The practice of the web-based simulation as well as the … …Journal of Computer Science, Vol. 3, Issue 10 · 31 Oct 2007 · 6,982 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordModeling and Simulation of a Novel Switched Reluctance Motor Drive System with Power Factor ImprovementG. Venkatesan, R. Arumugam, M. Vasudevan et al.This study presents a novel Switched Reluctance Motor (SRM) drive system with power factor improvement. Recently, many of the converters with variable speed drives have no input power factor correction circuits. This results in harmonic pollution of the utility supply, which should be avoided. The effect of power factor variation in terms of harmonic content is also analyzed in this … …American Journal of Applied Sciences, Vol. 3, Issue 1 · 31 Jan 2006 · 7,096 accessesView PDFCite
