Research ArticleOpen accessAll words, across the recordEconomical Investigation of ICECHP Using Gasohol-A Case Study for IranIman Baratian, Barat Ghobadian, Mohammad AmeriEnergy is one of the most important factors in strategic planning throughout the world and can be considered as a dominant driving force for the industry and world economy. Biofuels development and applications specially in the form of Combined Heat and Power using Internal Combustion Engine (ICECHP) is wide-spreading which is the subject matter of the present paper as its … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 6,915 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordExperimental Study of Near Wake Flow Behind a Rectangular CylinderAbdollah Shadaram, Mahdi Azimi Fard, Noorallah RostamyThe turbulence characteristics of the near wake flow behind a rectangular cylinder is investigated in a two-dimensional analysis using a hot-wire anemometer. The time-averaged and fluctuating components of the velocity are measured for a cylinder having various width-to-height (b h-1) ratios. The measurements are carried out in a low-speed wind tunnel. Data from hot-wire anemometer is collected by a data … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 7,270 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordContribution of the Entropy Function to the Study of Collimator for Nuclear Medicine ImagingM.S. Bouhdima, I. Elloumi, M.H.B. GhozlenScintigraphic image currently used in the diagnosis or the evaluation process of tissues, is strongly dependant on several technical parameters specially collimator characteristics. The present work describes a numerical method, based on entropy function, able to specify depth and hole diameter of collimator as well as other geometrical parameters to get a better accuracy in scintigraphy evaluation. From the classical … …American Journal of Applied Sciences, Vol. 4, Issue 10 · 31 Oct 2007 · 6,737 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordNumerical Study of the Moving Boundary Problem During Melting Process in a Rectangular Cavity Heated from BelowY. Jellouli, R. Chouikh, A. Guizani, A. BelghithWe present an analysis of the melting process in Phase Change Materials (PCM) in a horizontal cavity heated from below, driven by the coupling of transient heat conduction in the solid phase and steady state laminar natural convection in the liquid phase with one of the boundaries of the solution domain that moves. We state the problem in the Cartesian … …American Journal of Applied Sciences, Vol. 4, Issue 4 · 30 Apr 2007 · 7,391 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordExperimental Study of Parameters Influencing the Purity of Potassium Sulfate Fertilizer Produced from Jordanian Raw MaterialsMousa GougazehThe general objective of the present investigation was to make a contribution towards improving the purity of the produced potassium sulfate from (KCl, Arab Potash Company-Dead Sea) and (H2SO4, Jordanian Phosphate Company). The process parameters influencing the contamination of the poisoning chlorine within the product were experimentally investigated. The experiments were performed in a small-scale batch reactor equipped with a … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 7,042 accessesView PDFCite
