Research ArticleOpen accessIn the abstractGas Atomization of Molten Metal: Part II. ApplicationsTaher M. Abu-Lebdeh, Genaro Pérez-de León, Sameer A. Hamoush et al.A numerical model was derived to obtain results for two alloys during the Gas Atomization (GA) method. The model equations and governing equations were implemented through the application of part I data. Aspects such as heat transfer, fluid mechanics, thermodynamics and law of motions were taken into account for the formulation of equations that take gas dynamics, droplet dynamics and … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 19 Apr 2016 · 8,359 accessesView PDFCite
Research ArticleOpen accessIn the abstractGas Atomization of Molten Metal: Part I. Numerical Modeling ConceptionGenaro Pérez-de León, Vincent E. Lamberti, Roland D. Seals et al.This numerical analysis study entails creating and assessing a model that is capable of simulating molten metal droplets and the production of metal powder during the Gas Atomization (GA) method. The essential goal of this research aims to gather more information on simulating the process of creating metal powder. The model structure and perspective was built through the application of … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 10 Apr 2016 · 9,047 accessesView PDFCite
Research ArticleOpen accessIn the abstractON THE RELIABILITY OF REYNOLDS-AVERAGED NAVIER STOKES PREDICTION OF MEAN FLOW CHARACTERISTICS OF A RECTANGULAR TURBULENT JET IN CROSSFLOWE. Khali, Y. F. YaoA jet of fluid discharging into a cross stream, also known as Jet In Crossflow (JICF), has received many experimental and numerical investigations. In addition to the fundamental understanding of three-dimensional mixing and shear flow characteristics, the fluid dynamics research community often regarded it as a benchmark test case for validating turbulence models. Although many authors considered the canonical case … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 30 Sep 2014 · 6,958 accessesView PDFCite
Research ArticleOpen accessIn the abstractTHE 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
Research ArticleOpen accessIn the abstractFINITE VOLUME METHOD OF MODELLING TRANSIENT GROUNDWATER FLOWN. Muyinda, G. Kakuba, J. M. MangoIn the field of computational fluid dynamics, the finite volume method is dominant over other numerical techniques like the finite difference and finite element methods because the underlying physical quantities are conserved at the discrete level. In the present study, the finite volume method is used to solve an isotropic transient groundwater flow model to obtain hydraulic heads and flow … …Journal of Mathematics and Statistics, Vol. 10, Issue 1 · 15 Feb 2014 · 7,108 accessesView PDFCite
Research ArticleOpen accessIn the abstractFire Design: Direct Comparison Between Fire Curves. The Case Study of a NurseryMara Lombardi, Giuliano Rossi, Nicolò Sciarretta, Nino OrangesAccording to fire safety engineering, the present study analyzes fire design settings for simulation of fire in a nursery and proposes to compare simulations developed with a natural fire curve and nominal fire curve. Comparative analysis was developed according to thermo-fluid dynamic parameters that are relevant to the safety of the exposed and for the representative period of the danger … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 3 · 9 Sep 2013 · 7,345 accessesView PDFCite

Research ArticleOpen accessIn the abstractA Simplified Analytical Modeling of the Hole Erosion TestMohammed Bezzazi, Abdellatif Khamlichi, Miguel Prron Vera et al.Problem statement: Internal erosion occurs in soils containing fine particles under the action of high pressure gradients that could result from water discharge. This phenomenon can yield in its final stage to the formation of piping which constitutes a real threat for hydraulics infrastructures as it can precipitate their entire rupture in very short time. In order to mitigate this … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 30 Nov 2010 · 8,025 accessesView PDFCite
Research ArticleOpen accessIn the abstractFully Integrated Hydrocarbon Reservoir Studies: Myth or Reality?Christoforos Benetatos, Dario VibertiProblem statement: In the petroleum industry and especially during reservoir studies, data coming from different disciplines must be combined in order to generate a model that is representative of the reservoir being studied and can be used for defining the most viable development strategy of the field from both an economic and technical standpoint. Each of these disciplines represents an … …American Journal of Applied Sciences, Vol. 7, Issue 11 · 8 Nov 2010 · 9,975 accessesView PDFCite
