Research ArticleOpen accessIn the abstractDYNAMIC ENERGY MODELING OF AN EXPERIMENTAL BUILDING EQUIPPED WITH AN UNDERFLOOR AIR DISTRIBUTION (UFAD) SYSTEMYao Yu, Ahmed Cherif MegriIn this study, experimental and simulation studies were performed in a building equipped with an UFAD system in order to investigate the applicability of a new approach designed for prediction of the energy consumption of a residential building with an UFAD system. In this approach, a zonal model, Pressurized zOnal Model with the Air diffuser (POMA), was coupled with a … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 14 Mar 2014 · 8,136 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerception Mapping of Travelers: Case of Six Indian Domestic AirlinesShobhit Agarwal, A. K. DeyProblem statement: A comparison of customer satisfaction based on service quality as perceived by air travelers was done among six domestic airlines. Literature review suggested that flying experience has three stages: Pre-flight, in-flight and post-flight and a set of six variables can be used to measure satisfaction. These variables are: Ease of bookings through the website/call center; Hassle free check … …American Journal of Economics and Business Administration, Vol. 2, Issue 2 · 30 Jun 2010 · 7,446 accessesView PDFCite
Research ArticleOpen accessIn the abstractFocusing of the Flow Capture for Local Exhaust Ventilation SystemsS. Y. Spotar, A. L. SorokinProblem statement: The extraction hoods commonly used as inlet element of the local ventilation systems exhibit limited emission capture over moderate distances from the source of the hazardous emissions. Proposed inclusion of a swirling peripheral jet was found to increase the effective length over which the extraction hood successfully captures harmful fumes. However information on a detailed pattern field of … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 7,329 accessesView PDFCite
Research ArticleOpen accessIn the abstractGlassy Amorphous Metal Injection Molded Induced Morphological DefectsRaffaella Aversa, Daniela Parcesepe, Relly Victoria V. Petrescu et al.Melt rheology in injection molded metastable supercooled liquid metal of Zr44-Ti11-Cu10-Ni10-Be25 alloy may induce selective crystallizations. High mobility Be, Cu and Ni atoms have been observed to differently crystallize in bulk metal glassy supercooled liquids. Here, we analyze the result of morphological microscopic observation conduct on Bulk Metallic Glass (BMG) with composition of a commercial liquid metal alloy (LM001B). The … …American Journal of Applied Sciences, Vol. 13, Issue 12 · 27 Dec 2016 · 8,938 accessesView PDFCite
Research ArticleOpen accessIn the abstractSIMULATION OF THE PROCESS OF FLOW SEPARATION AT THE ENTRANCE OF SQUARE ASPIRATING PORTOlga A. Averkova, Ilya V. Kryukov, Kirill V. Plotnikov et al.We consider the flow at the inlet to the suction square hole with sharp edges, which is located in an infinite space. The purpose of this study is to construct a mathematical model of flow separation at the entrance to square suction canal with sharp edges, located in infinite space, by using square vortex frameworks. As a part of ideology … …American Journal of Environmental Sciences, Vol. 10, Issue 5 · 12 Nov 2014 · 6,681 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeat Transfer Augmentation for Electronic CoolingSuabsakul GururatanaProblem statement: The performance of electronic devices has been improving along with the rapid technology development. Cooling of electronic systems is consequently essential in controlling the component temperature and avoiding any hot spot. The study aims to review the present electronic cooling methods which are widely used in electronic devices. Approach: There are several methods to cool down the electronics … …American Journal of Applied Sciences, Vol. 9, Issue 3 · 2 Feb 2012 · 7,712 accessesView PDFCite
Research ArticleOpen accessIn the abstractComposition-Explicit Distillation Curves of Waste Lubricant Oils and Resourced Crude Oil: A Diagnostic for Re-Refining and EvaluationLisa Starkey Ott, Beverly L. Smith, Thomas J. BrunoProblem statement: We have recently introduced several important improvements in the measurement of distillation curves for complex fluids. The modifications include a composition-explicit data channel for each distillate fraction and temperature measurements that are true thermodynamic state points that can be modeled with an equation of state. The composition-explicit information is achieved with a sampling approach that allows precise qualitative … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 8,101 accessesView PDFCite

Research ArticleOpen accessIn the abstractStudies on the Influence of Various Blade Outlet Angles in a Centrifugal Pump when Handling Viscous FluidsM.H.S. Fard, F.A. BoyaghchiIn this study the centrifugal pump performances with different blade outlet angles are tested when handling water and viscous oils as Newtonian fluids. Also, this study shows a numerical simulation of the three-dimensional fluid flows inside the centrifugal pump with different blade outlet angles. For these numerical simulations the SIMPLEC algorithm is used for solving governing equations of incompressible viscous/turbulent … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 7,706 accessesView PDFCite
