Research ArticleOpen accessIn the abstractThe Effect of Electricity Price on Saving Energy Transmitted from External Building WallsSamah K. Alghoul, Ammar O. Gwesha, Abdurrauf M. NaasSpace heating and cooling loads consume a significant part of the national produced energy in many countries. Therefore, substantial energy savings can be achieved by the reduction of spent energy in this category. Since wall insulation is rarely used in Libya, this research was conducted to study the effect of electricity price on residential heating and cooling energy consumption and … …Energy Research Journal, Vol. 7, Issue 1 · 31 May 2016 · 10,846 accessesView PDFCite
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 · 8,365 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Prototype of a Small-Scale Solar Power Plant: dynamic Simulation and Thermoeconomic AnalysisAnnamaria Buonomano, Francesco Calise, Maria VicidominiThe paper presents an innovative prototype of a solar power plant, purposely designed for small-scale applications such as residential and/or small commercial buildings. The system consists of 10 kWe Organic Rankine Cycle (ORC) plant and innovative solar thermal collectors. In particular, 235 m2 of flat-plate evacuated solar collectors are designed to heat diathermic oil up to 180°C. A variable volume … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 8 Feb 2016 · 8,065 accessesView PDFCite
Research ArticleOpen accessIn the abstractStructural Dynamics of the Distribution Mechanism with Rocking Tappet with RollFlorian Ion T. Petrescu, John Kaiser Calautit, Dragan MarinkovicIn this study, the authors present a new method to dynamically synthesize a mechanism with rotary cam and rotated tappet with roll, used with priority at the distribution mechanisms from the heat engines with internal combustion. This type of distribution can improve the changes of gases and may decrease significantly the level of vibration, noises and emissions. As long as … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 28 Oct 2015 · 9,294 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Solid Residues Obtained from Supercritical Ethanol Liquefaction of Swine ManureRui Li, Bo Zhang, Shuangning Xiu et al.Animal wastes are considered as renewable energy resources, which contain a great energy potential. For this study, swine manure was treated with supercritical ethanol within the reaction temperature range of 240-360°C to produce bio-oil, resulting in a significant amount of solid residues. Solid residues were characterized by using Fourier Transform Infrared (FT-IR), Scanning Electron Microscopic (SEM), surface area, elemental and … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 15 Jul 2015 · 7,696 accessesView PDFCite
Research ArticleOpen accessIn the abstractA DC-DC Circuit Using Boost Converter for Low Voltage Energy Harvesting ApplicationNurul Arfah Che Mustapha, A.H.M. Zahirul Alam, Sheroz Khan, Amelia Wong AzmanA DC-DC step-up voltage converter is designed to convert a very low voltage supply, 35 mV such as from the thermal energy source from body heat. The converter can generate an output voltage up to 210 mV, approximately six imes its initial input voltage over a frequency of 36 GHz. The effect of switching transistors, inductor current, rise and fall … …American Journal of Applied Sciences, Vol. 12, Issue 4 · 9 Jun 2015 · 6,985 accessesView PDFCite
Case ReportOpen accessIn the abstractImpacts of Biogas Digestate on Crop Production and the Environment: A Bulgarian Case StudyNicholas Kathijotes, Vera Petrova, Elena Zlatareva et al.The water-energy nexus reveals that large amounts of energy is stored in used water and can be used as an energy source. Anaerobic fermentation is an excellent ecological waste treatment and a way of producing low cost electrical and thermal energy. By using digestate resulting from biogas production instead of synthetic fertilizers derived from natural gas, we can save energy, … …American Journal of Environmental Sciences, Vol. 11, Issue 2 · 29 May 2015 · 7,558 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessing the Lignin Fraction Extracted from Brazilian Energy CropsDiogo José Horst, Jhon Jairo Ramírez Behainne, Pedro Paulo de Andrade Junior, Luís Filippe SerpeThis study quantifies the extraction performance and some properties of the lignin obtained from six crops with potential for generating thermal energy in Brazil. A full factorial design (22) with four replicates including two extraction methods and two particles size distributions was adopted for assessing the fraction of lignin, as well as its Higher Heating Value (HHV) and composition given … …American Journal of Environmental Sciences, Vol. 11, Issue 1 · 27 Apr 2015 · 7,582 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Dynamic Simulation of a Combined System Integration Concentrating Photovoltaic/Thermal Solar Collectors and Organic Rankine CycleFrancesco Calise, Massimo Dentice d'Accadia, Maria Vicidomini et al.This study presents the design of a novel ultra-high efficient solar power system. The system is equipped with a concentrating PhotoVoltaic/Thermal (CPVT) solar collectors bottomed by an Organic Rankine Cycle (ORC). The basic idea is to use a high temperature CPVT device producing simultaneously electricity and hot diathermic oil. Then, this hot fluid is used to supply heat to the … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 17 Apr 2015 · 8,659 accessesView PDFCite
