Research ArticleOpen accessIn the keywordsDevelopment and Validation of a 2D Finite Element Model for Air Pollution Dispersion (SUITE-2D)Youssef Ismail HafezThis paper presents the development and validation of SUITE-2D (Solving Unsteady Incompressible Transport Equation in Two Dimensions), a two-dimensional finite element model for solving the advection-diffusion transport equation with decay and source terms. The model provides an efficient and accurate approach for simulating pollutant dispersion in environmental systems. The finite element formulation uses the standard Galerkin method, with numerical integration … …American Journal of Environmental Sciences, Vol. 21, Issue 1 · 22 Dec 2025 · 3,127 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Experimental Comparison for Compression of PLA Specimens Printed in In-Plane and Out-of-Plane DirectionsSalvatore Brischetto, Roberto TorreThe present work proposes an experimental comparison between the in-plane and out-of-plane compressive behaviors of 3D printed PolyLactic Acid (PLA) specimens. These specimens are produced via the Fused Deposition Modeling (FDM) technique by using two different printing directions: the first printing direction in the xz plane allows experimental compression tests in the out-of-plane direction; the second printing direction in the … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 3 · 25 Sep 2020 · 7,648 accessesView PDFCite
Research ArticleOpen accessIn the abstractANSYS Numerical Modeling of Confined Deep Beam with High Strength ConcreteSyahril Taufik, Elia Anggarini, Ichwan SetiawanIn the numerical modeling presented, the deep beam is accounted for by means of a three dimensional FEA ANSYS 13.0 approach, in which the structure is modeled with load-displacement-based solid finite elements, whereas the internal work structure interacted by high strength concrete and reinforcement in full scale. Most deep beam collapse is dominated by the shear brittle collapse. Recently, confinement … …International Journal of Structural Glass and Advanced Materials Research, Vol. 4, Issue 1 · 10 Feb 2020 · 6,953 accessesView PDFCite
Research ArticleOpen accessIn the abstractPetrophysical Properties Distribution Modelling of an Onshore Field, Niger Delta, NigeriaGodwin Omokenu EmujakporueThis research is based on the modelling of petrophysical parameters distribution of an onshore oil field in Niger Delta. The methodology involves the construction of 3-D grids that represent the reservoir geometry, accompany by property modeling where the 3-D grids were populated with petrophysical properties (porosity, water saturation, net to gross ratio, facies and permeability). The objective is to construct … …Current Research in Geoscience, Vol. 7, Issue 1 · 3 Apr 2017 · 14,182 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 · 7,183 accessesView PDFCite
Research ArticleOpen accessIn the abstractCoupled Hydrodynamic-Water Quality Model for Pollution Control Scenarios in El-Burullus Lake (Nile Delta, Egypt)A. El-Adawy, A. M. Negm, O. C. Saavedra V et al.El-Burullus Lake is affected by increasing and extensive human activities, rapid social-economic development and the construction of fish ponds nearby. This has significantly impacted the health of the lake eco-system. On the foundation of the two-dimensional depth averaged hydrodynamic model, distributions of the salinity, Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and Ammonium (NH4) were modeled. … …American Journal of Environmental Sciences, Vol. 10, Issue 6 · 10 Nov 2014 · 7,207 accessesView PDFCite
Research ArticleOpen accessIn the abstractSilicone Modeling of the Interior Spaces of Hollow Organs: Use in Dog and Manatee Respiratory Tract and in a Beef HeartCharles J. Grossman, Richard Hamilton, Lisa A. Close-Jacob et al.Problem statement: The mechanism, by which the Florida manatee (Trichechus manatus latirostris) vocalizes, remains unknown because the manatee larynx does not contain true vocal cords. Since sound can be generated when air passes through a narrow respiratory structure we needed to visualize the internal anatomy of manatee respiratory tract to locate any candidate regions for study. Approach: To visualize the … …OnLine Journal of Biological Sciences, Vol. 11, Issue 1 · 6 Jul 2011 · 7,803 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 abstractControl of a Step Walking Combined to Arms Swinging for a Three Dimensional Humanoid PrototypeAmira Aloulou, Olfa BoubakerProblem statement: Present researches focus to make humanoid robots more and more autonomous so they can assist human in daily works like taking care of children, aged or disabled persons. In such social activities, the contemporary humanoid robots are expected to have human like morphology and gait. Studies on bipedal locomotion for humanoid robots are then part of the hottest … …Journal of Computer Science, Vol. 6, Issue 8 · 31 Aug 2010 · 7,419 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Study of Airflow around Vehicle A-pillar Region and Windnoise Generation PredictionM. H. Shojaefard, K. Goudarzi, H. FotouhiFlow separation and reattachment around the vehicle A-pillar region dictates strong pressure fluctuations on the side window surfaces and can also lead to generate aerodynamic noise. The objective of this work is to investigate qualitative flow visualization of airflow behaviour around vehicle A-pillar and its potential to generate windnoise in this region. By means of Computational Fluid Dynamic (CFD) under … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,335 accessesView PDFCite
