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 · 8,061 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving the Approaches to Planning the Electricity Consumption in Budget InstitutionsNailya Malikovna Yakupova, Rezeda Muhtarovna Kundakchyan, Roza Nuriahmetovna Andreeva, Aleksey Vladimirovich AndreevThe technique of predicting the budget organizations' electrical power demands, which is currently used in Tatarstan Republic, based on the averaged norms for all educational establishments, does not reflect the impact of certain external and internal factors of environment influencing the volume of energy consumption, which results in the inefficient expenditure of the budget. This problem is especially topical for … …American Journal of Applied Sciences, Vol. 12, Issue 12 · 26 Nov 2015 · 6,378 accessesView PDFCite
Research ArticleOpen accessIn the abstractElectrical Properties of Cobalt Oxide/Silica Nanocomposites Obtained by Sol-Gel TechniqueGomaa A.M. Ali, Osama A. Fouad, Salah A. MakhloufThis work is an extension of our previous studies on cobalt oxide nanoparticles impeded in a silica matrix. Here we study the preparation and characterization of high cobalt content materials (60-90 wt%). In addition, the DC electrical conductivity of the prepared materials in a wide temperature range (350-673 K) was measured and discussed. The activation energy has been obtained according … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 18 Nov 2015 · 8,678 accessesView PDFCite
Research ArticleOpen accessIn the abstractDegradation of Power Generation Performance due to Effects of Various Ice Shapes and Accretions on Wind Turbine BladesAditya Bagade, Changki Mo, Abdelhamid MazherIn today’s world, green energy has become a key initiative as an alternative energy resource. Wind turbines are widely used to harvest wind energy in seasonal and cold environments. Although efficient, cold weather conditions negatively affects wind turbine operations due to ice formation. Damage from icing is seen on blade-tips when super-cooled water droplets that form in colder environments rapidly … …Energy Research Journal, Vol. 6, Issue 2 · 11 Sep 2015 · 7,815 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 · 7,553 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 · 8,654 accessesView PDFCite
Research ArticleOpen accessIn the abstractELECTROLYSIS OF SWINE MANURE EFFLUENTS USING THREE DIFFERENT ELECTRODES Fe-Fe, Al-Al AND Fe-AlS. Rahman, M. S. BorhanSwine effluent with high organic strength need to be treated to make it suitable for applying to crop/pasture fields, or discharging to any waterways. Electrocoagulation is a relatively simpler and cheaper technique over biological and chemical treatment methods currently used to treat high-strength industrial and municipal wastewater. The performance of an electrocoagulation system mainly depends on the pH, Electrical Conductivity … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 4 · 9 Oct 2014 · 9,177 accessesView PDFCite
Research ArticleOpen accessIn the abstractENERGY AND ENVIRONMENTAL EVALUATION OF MICRO-COGENERATION SYSTEM FOR CONVENIENCE STORES IN THAILANDSuapphong Kritsanawonghong, Weijun Gao, Pawinee Iamtrakul, Soichiro KurokiThe growing worldwide demand for effective energy utilization has led to numerous techniques for rational use of energy including conservation techniques and renewable energy utilization. Recently, the number of small scale buildings such as minimarts and convenience stores in Thailand has increased rapidly. However, the interest of effective energy utilization has not been focused on the implementation of the new … …American Journal of Environmental Sciences, Vol. 10, Issue 3 · 15 May 2014 · 7,450 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Architecture of Maximum Power Point Tracking for Ultra-Low-Power Based Hybrid Energy Harvester in Ubiquitous Devices: A ReviewMichelle Lim Sern Mi, Sawal Hamid Muhammad Ali, Md Shabiul IslamThis research work presents a novel architecture of an Ultra-Low-Power (ULP) based Hybrid Energy Harvester (HEH) consisting of multiple input sources such as kinetic, thermal and solar energy, harvested from passive human power. Having multiple ambient sources mitigates limitations caused by single sources especially for bodily-worn applications; however, this results in impedance mismatch among the different integrated sources. To overcome … …American Journal of Applied Sciences, Vol. 10, Issue 10 · 6 Sep 2013 · 7,155 accessesView PDFCite
Research ArticleOpen accessIn the abstractAttaining the Room Comfort by Solar Reflective PaintM. Sakthivel, M. Sekar, C. Ramesh, S. Satheesh KumarThe objective of this research was to provide the Room comfort by means of Solar Reflective Paint (SRP) on the roof and thereby reducing the consumption of electrical energy. Solar heat diffuses through roof into the room resulting in human discomfort. Human discomfort leads to the usage of electrical energy. Valuable energy has to be conserved.
