Research ArticleOpen accessIn the abstractComparative Performance of Direct Injection Diesel Engines Fueled Using Compressed Natural Gas and Diesel Fuel Based on GT-POWER SimulationSemin, Abdul R. Ismail, Rosli A. BakarThe paper is investigated the application of compressed natural gas (CNG) as an alternative fuel and its performance effect in the diesel engines using GT-POWER computational simulation. The CNG as an alternative fuel for four stroke diesel engine modeling was developed from the real diesel engine using GT-POWER computational model with measure all of engine components size. The computational model … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 7,314 accessesView PDFCite
Research ArticleOpen accessIn the abstractComputational Visualization and Simulation of Diesel Engines Valve Lift Performance Using CFDSemin, Rosli Abu Bakar, Abdul Rahim IsmailThe paper visualized and simulated the intake and exhaust valve lift in the single-cylinder four-stroke direct injection diesel engine. The visualization and simulation computational development were using the commercial Computational Fluid Dynamics of STAR-CD 3.15A software and GT-SUITE 6.2 software. The one dimensional of valve lift modeling was developed using GT-POWER software and the visualization the model using STAR-CD. The … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 6,939 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Analysis of Pulsatile Blood Flow in a Stented Human Coronary Artery with a Flow DividerVahab Dehlaghi, Mohammad Tafazoli Shadpoor, Siamak NajarianShear stress is known to play a central role in restenosis formation and is sensitive to stent geometry. Local flow alterations created by a different stents without and with flow divider were studied to compare the hemodynamic effects of Stent design properties on restenosis in stented human coronary artery. Blood pressure and shear stress values were computed in three different … …American Journal of Applied Sciences, Vol. 4, Issue 6 · 30 Jun 2007 · 6,523 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Simulation of a Turbulent Lean, Premixed Combustion with an Explicit Algebraic Stress ModelWilliam Vicente, Martín Salinas-Vázquez, Eliseo Martínez, Alejandro RodríguezA computational model is used in the present paper to study the influence of the turbulence modeling on the chemical species in a turbulent lean premixed flame. The simulated configuration is about a lean, premixed bluff-body-stabilized flame with a recirculation zone. To achieve the objectives, three different models were used for turbulence modeling as listed next: 1) standard k-ε, 2) … …Journal of Mathematics and Statistics, Vol. 1, Issue 2 · 30 Jun 2005 · 6,319 accessesView PDFCite
Research ArticleOpen accessIn the abstractPersian Curve Versus Monte Carlo MethodAbdolrasoul Ranjbaran, Mohammad Ranjbaran, Fatema RanjbaranThe Monte Carlo Simulation method is a powerfultool for solving problems including random variables. The basic idea toimplement a Monte Carlo simulation is to first generate samples of randominputs from their assumed distributionfunctions and then perform a deterministic calculation on the generated randominputs, based on mathematical modeling of the system, to obtain output results.An early version of Monte Carlo simulation … …International Journal of Structural Glass and Advanced Materials Research, Vol. 5, Issue 1 · 6 Jul 2021 · 8,304 accessesView PDFCite
Research ArticleOpen accessIn the abstractStructural Performance of Double Laminated Glass Panels with EVA and PVB Interlayer in Four-Point Bending TestsTomáš Hána, Martina Eliášová, Zdeněk SokolMany examples of glass loadbearing structures such as handrails, panes, beams and columns can be found in modern architecture. Most of these elements are made of laminated glass panels. There is a general lack of knowledge about the transfer of shear forces between the glass plies in perpendicularly-loaded laminated panels. This transfer depends significantly on the stiffness of the polymeric … …International Journal of Structural Glass and Advanced Materials Research, Vol. 2, Issue 1 · 14 Aug 2018 · 13,283 accessesView PDFCite
Research ArticleOpen accessIn the abstractQuantization of Map-Based Neuronal Model for Embedded Simulations of Neurobiological Networks in Real-TimeNikolai F. Rulkov, Ariel Mark Hunt, Peter N. Rulkov, Andrey G. MaksimovThe discreet-time (map-based) approach to modeling nonlinear dynamics of spiking and spiking-bursting activity of neurons has demonstrated its very high efficiency in simulations of neuro-biologically realistic behavior both in large-scale network models for brain activity studies and in real-time operation of Central Pattern Generator network models for biomimetic robotics. This paper studies the next step in improving the model computational … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 9 Nov 2016 · 8,778 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of the Interaction between the Lining of a TBM Tunnel and the Ground Using the Convergence-Confinement MethodPierpaolo OresteThe support used when a tunnel is excavated by a shielded TBM is complex because it consists of two different materials: A concrete segmental lining and a filler annulus between the lining and the tunnel wall. A detailed analysis of the behavior of such a support system requires a three-dimensional numerical modeling and should also consider the presence of the … …American Journal of Applied Sciences, Vol. 12, Issue 4 · 17 Jun 2015 · 7,191 accessesView PDFCite
Research ArticleOpen accessIn the abstractA NOVEL PRESSURIZED ZONAL MODEL USING THE MOMENTUM EQUATIONYao Yu, Ahmed Cherif MegriZonal models combine the simplicity of single and multi-zone models with the comprehensiveness of Computational Fluid Dynamics (CFD) models and thus become a better substitute to predict detailed thermal and airflow behaviors in building. Based on a geometric partitioning of a room into a number of subzones, these models give more accurate and detailed results than the single or multi-zone … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 25 Mar 2014 · 8,574 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Implementation of Parallel Subunit for Synthesis Mathematical ModelsIssa M. ShehabatProblem statement: Mathematical modeling of different natural and technical objects and processes is one of the most important directions that needs high performance computing with huge memory. To reduce the computational time and expenses we need to carry out the calculations on specialized subunits. Approach: We described a self-organizing approximation method and introduced a new methodology of structural synthesis of … …Journal of Computer Science, Vol. 6, Issue 3 · 31 Mar 2010 · 6,922 accessesView PDFCite
