Research ArticleOpen accessIn the abstractForecasting of Energy Consumption and Pollutant Emission for Road Transportation Policies EvaluationPunravee Kongboontiam, Rungsun UdomsriProblem statement: The energy demand in Thailand has significantly increased over last ten years, particularly in transportation sector. Road transportation contributes the highest energy consumption, 38% of the total energy in the whole country, but it consumes 60% of the total energy usage in the northern region of Thailand. Various chemical pollutants emitted from the road transportation affecting to human … …Energy Research Journal, Vol. 2, Issue 1 · 23 Jan 2012 · 7,720 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnergy Option for Small Scale Cashew Nut Processing in IndiaAtul Mohod, Sudhir Jain, A.G. PowarProblem statement: Cashew (Anacardium Occidentale L.) is one of the important tropical crops. India processed about 11,80,000 metric tons of raw cashew nut seeds through 3650 cashew processing industries scattered in many states of country. The cashew nut processing industries are typically located in the rural and backward areas. The most significant difficulty in processing cashew nuts is that the … …Energy Research Journal, Vol. 1, Issue 1 · 30 Jun 2010 · 16,074 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Size of Heated Obstruction within Room on Three Dimensional Air Flow CharacteristicsAbduljabbar Muttair Ahmed, Mukhtar Ahmad, Abdur RahimProblem statement: This study reported a numerical investigation of three-dimensional turbulent buoyant recirculating flow within a room with heated obstruction. Approach: The study involved the solution of partial differential equations for the conservation of mass, momentum, energy, concentration, turbulent energy and its dissipation rate. These equations were solved together with algebraic expressions for the turbulent viscosity and the heat diffusivity, … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 6,934 accessesView PDFCite
Research ArticleOpen accessIn the abstractCombustion of Bimodal Nano/Micro Aluminum Suspension with New Reaction Rate ModelM. Bidabadi, N. Moallemi, I. Shafieenejad, M. JadidiIn this study a mathematical model for combustion of bimodal particle in lean flow was developed. The difference between structure of flame in this work and previous ones was that, in those flame was divided by five zones and reaction rate was considered to be constant in reaction zones and also zero in post flame zone. In reality it was … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 6,794 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Comparison of Thermal Stratification due Natural Convection in Densified LOX, LN2 TanksSeyed Ali Jazayeri, Ehsan Molla Hasanzadeh KhoeiThe growth of natural circulation and thermal stratification inside LOX, LN2 storage tanks due to heat transfer from surroundings is investigated using a non-equilibrium, two-domain, mathematical model. The two-dimensional model is considered for the liquid domain in two cases and a lumped, thermodynamic model is utilized for vapor domain. The vapor is assumed to behave like an ideal gas. The … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 6,967 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnergy Aware Optimal Routing for Wireless Sensor NetworksS. Chandramathi, U. Anand, T. Ganesh et al.Wireless Sensor Network (WSN) is a collection of autonomous devices with computational, sensing, and wireless communication capabilities. The sensor nodes are low cost, multi-functional devices that are densely deployed either inside the phenomenon or very close to it and are often powered by independent power sources. The lifetime of such sensor nodes show a strong dependence on lifetime of the … …Journal of Computer Science, Vol. 3, Issue 11 · 30 Nov 2007 · 6,645 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Simulation of an Absorption Diffusion Solar Refrigeration UnitB. Chaouachi, S. GabsiThe purpose of this study was the design and the simulation of an absorption diffusion refrigerator using solar as source of energy, for domestic use. The design holds account about the climatic conditions and the unit cost due to technical constraints imposed by the technology of the various components of the installation such as the solar generator, the condenser, the … …American Journal of Applied Sciences, Vol. 4, Issue 2 · 28 Feb 2007 · 7,677 accessesView PDFCite
Research ArticleOpen accessIn the abstractConservation of “Partial Vorticity” with Application on Hydraulic JumpsHarald NaeserIn two preceding works, the idea of partial conservation theorems was introduced and conservation equations for partial energy and partial angular momentum were established. A similar conservation theorem for partial vorticity of incompressible fluids is established here. The vorticity vector is divided into two elements (both denoted “partial vorticity”) and their conservation equations established separately. They show that, in addition … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 6,704 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermal Energy Loss in the Steam Valves and its EffectsGalip Temir, Durriye BilgeIn this study, the effects of thermal losses in steam valves for flow have been analyzed. In a set of experiment built to achieve this, pressure and condensate values have been calculated in different temperatures for insulated and non-insulated cases in three different nominal diameter steam valves. The amount of energy lost from the valve surface in the natural convection … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 7,202 accessesView PDFCite
