Research ArticleOpen accessIn the keywordsOn the Closed Form Solutions of Linear and Nonlinear Cauchy Reaction-Diffusion Equations Using the Hybrid of Fourier Transform and Variational Iteration MethodS.S. Nourazar, A. Nazari-Golshan, M. NourazarProblem statement: In the present study, a hybrid of Fourier transform and Variational Iteration Method (FTVIM) is developed for solving the non-homogeneous linear and nonlinear partial differential equations of Cauchy reaction-diffusion problem. Approach: The closed form solutions obtained from the series solution of recursive sequences is valid for the entire range of problem domain. Results and Conclusion: Moreover, the very … …Physics International, Vol. 2, Issue 1 · 26 Oct 2011 · 8,195 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOptical Properties of Crosslinked Chitosan Thin Film with Glutaraldehyde Using Surface Plasmon Resonance TechniqueYap Wing Fen, W. Mahmood Mat Yunus, Mohd Maarof Moksin et al.Problem statement: The aim of this research is to study the optical properties of crosslinked chitosan thin film with glutaraldehyde using Surface Plasmon Resonance (SPR) technique. Approach: The crosslinked chitosan is synthesized by homogeneous reaction of medium molecular weight chitosan in aqueous acetic acid solution with glutaraldehyde as crosslinking agent. Four different amount of chitosan, i.e., 0.40, 0.50, 0.60 and … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 28 Jan 2011 · 9,624 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeat Transfer Numerical Analysis of a Thermochemical Solar ReactorA. Vázquez-Rodríguez, J. R. Varela-Ham, R. Avalos-Zuñiga et al.In this study a 2D transient temperature distribution in a one-dimensional thermochemical solar reactor of gas-particles is presented. The gas-particles medium is contained in a reactor where an endothermic chemical reaction of some oxide-metal at high temperature is expected to be occurred. The reactor receives the concentrated solar power on the reactor walls, or directly to the gas-particles medium. As … …Energy Research Journal, Vol. 5, Issue 2 · 6 Jan 2015 · 6,803 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental and Skeletal Kinetic Model Study of Compressed Natural Gas Fueled Homogeneous Charge Compression Ignition EngineP. M. Diaz, B. Durga Prasad, D.S. Manoj Abraham, K. PalaniKumarProblem statement: In homogeneous charge compression ignition engines fuel oxidation chemistry determines the auto-ignition timing, heat release, reaction intermediates and the ultimate products of combustion. To shorten development time and to understand combustion processes, the use of simulation is increasing. Approach: A model that correctly simulates fuel oxidation at these conditions would be a useful design tool. Detailed models of … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 22 Mar 2012 · 7,255 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe 2D Eulerian Approach of Entrained Flow and Temperature in a Biomass Stratified Downdraft GasifierA. Rogel, Jasni AguillónThis paper describes a “1-D+2-D” numerical model used to simulate the gasification of pine wood pellets in a stratified downdraft gasifier whereby Eulerian conservation equations are solved for particle and gas phase components, velocities and specific enthalpies. The model takes into account the biomass particle process such as heating up, drying, primary pyrolysis of biomass, secondary pyrolysis of tar, homogeneous … …American Journal of Applied Sciences, Vol. 3, Issue 10 · 31 Oct 2006 · 7,252 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAn Investigation of Compressed Natural Gas Engine for Nitrogen Oxides ReductionP. M. Diaz, B. Durga PrasadProblem statement: This study describes the use of Reformer Gas (RG) to alter NOx emission in a CNG-fueled HCCI engine. Comparison with diesel, natural gas has a very high octane number (≈120) and high auto-ignition temperature (≈600°C). Composed mostly of methane, natural gas is the only common fuel to manifest relatively pure, single-stage combustion. Other fuels have stronger low-temperature reaction … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 15 May 2012 · 7,298 accessesView PDFCite
