Research ArticleOpen accessIn the abstractHydraulic Flow through Engineering Bentonite-Based Containment BarriersEric Wooi Kee Loh, Devapriya Chitral WijeyesekeraThis paper presents the use of software modelling as a tool to study the impact of hydraulic "resistivity" on the contaminant transport through bentonite-based containment barriers. A sensitivity analysis on the predicted data was carried out by varying the boundary conditions as well as the hydraulic resistance to flow through varying contaminant transport parameters. Accordingly, both advective and diffusive flow … …American Journal of Applied Sciences, Vol. 12, Issue 11 · 4 Nov 2015 · 6,703 accessesView PDFCite
Review ArticleOpen accessIn the abstractKinetic Models for Anaerobic Fermentation Processes-A ReviewEmmanuel Amagu EchieguA review of basic kinetic models describing the generation of biomass and utilization of substrates in anaerobic fermentation processes is presented as well as the stoichiometric and empirical models for the prediction of biogas production. The applications of these models to anaerobic reactor systems such as the CSTR, activated sludge, plug flow reactor, etc are also presented. These models are … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 3 · 24 Jul 2015 · 8,316 accessesView PDFCite
Review ArticleOpen accessIn the abstractProspects of Using Wastewater as a Resource-Nutrient Recovery and Energy GenerationMusfique Ahmed, Chowdhury Kamrul Hasan, Hafizur Rahman et al.It is well understood that both untreated and partially treated wastewater comprise substantial amount of resources, which can be recovered and utilized for different purposes. Since Waste Water Treatment Plant (WWTP) is energy intensive and expensive, substantiating the WWTPs with Resource Recover Technologies (RRTs) will not only save a considerable amount of energy but also make the environment cleaner and … …American Journal of Environmental Sciences, Vol. 11, Issue 2 · 25 Jun 2015 · 8,183 accessesView PDFCite
Research ArticleOpen accessIn the abstractUNSTEADY BOUNDARY LAYER FLOW ALONG A STRETCHING CYLINDER AN ANALYTICAL SOLUTIONM. Y. AklThe axisymetric laminar boundary layer unsteady flow along a continuously stretching cylinder immersed in a viscous and incompressible fluid is studied. The governing partial boundary layer equations in cylindrical form are first transformed into ordinary differential equations these equations are solved analytically using the optimal modified Homotopy Asymptotic method in order to get a closed form solution for the dimensionless … …Journal of Mathematics and Statistics, Vol. 10, Issue 2 · 17 Feb 2014 · 7,152 accessesView PDFCite
Research ArticleOpen accessIn the abstractWaste Heat Recovery from Boiler of Large-Scale Textile IndustryPrateep Pattanapunt, Kanokorn Hussaro, Tika Bunnakand, Sombat TeekasapMany industrial heating processes generate waste energy in textile industry; especially exhaust gas from the boiler at the same time reducing global warming. Therefore, this article will present a study the way to recovery heat waste from boiler exhaust gas by mean of shell and tube heat exchanger. Exhaust gas from boiler dyeing process, which carries a large amount of … …American Journal of Environmental Sciences, Vol. 9, Issue 3 · 21 Jun 2013 · 7,511 accessesView PDFCite
Research ArticleOpen accessIn the abstractGroundwater Flow Systems and Their Response to Climate Change: A Need for a Water-System View ApproachJoel J. Carrillo-Rivera, Antonio CardonaProblem statement: The interest in early hydrogeological studies was the aquifer unit, as it is the physical media that stores and permits groundwater transfers from the recharge zone to the discharge zone, making groundwater available to boreholes for water extraction. Approach: Recently, the aquifer concept has been complemented by the groundwater flow system theory, where groundwater may be defined by … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 7 Apr 2012 · 8,077 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpecifying Processes: Application to Electrical Power DistributionSabah Al-Fedaghi, Lina Al-SalehProblem statement: This study deals with the problem of how to specify processes. Many process specification methodologies have been determined to be incomplete; for example, ISO 9000:2005 defines process as transforming media inputs into outputs. Nevertheless, the author of the Quality Systems Handbook, declares that such a definition is incomplete because processes create results and not necessarily by transforming inputs. … …Journal of Computer Science, Vol. 7, Issue 11 · 6 Sep 2011 · 6,662 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling Malaysia's Energy System: Some Preliminary ResultsAhmad Mohd. YusofProblem statement: The current dynamic and fragile world energy environment necessitates the development of new energy model that solely caters to analyze Malaysia’s energy scenarios. Approach: The model is a network flow model that traces the flow of energy carriers from its sources (import and mining) through some conversion and transformation processes for the production of energy products to final … …American Journal of Applied Sciences, Vol. 8, Issue 9 · 13 Aug 2011 · 7,250 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdvective Heat Transport in an Unconfined Aquifer Induced by the Field Injection of an Open-Loop Groundwater Heat PumpStefano Lo Russo, Glenda TaddiaProblem statement: The increasing diffusion of low-enthalpy geothermal open-loop Groundwater Heat Pumps (GWHP) providing buildings air conditioning requires a careful assessment of the overall effects on groundwater system, especially in the urban areas. The impact on the groundwater temperature in the surrounding area of the re-injection well is directly linked to the aquifer properties. Physical processes affecting heat transport within … …American Journal of Environmental Sciences, Vol. 6, Issue 3 · 30 Jun 2010 · 7,970 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn-Cylinder Heat Transfer Characteristics of Hydrogen Fueled Engine: A Steady State ApproachM. M. Rahman, Khalaf I. Hamada, M. M. Noor et al.This study presents in-cylinder heat transfer characteristics of a single cylinder port injection Hydrogen fueled Internal Combustion Engine (H2ICE) using a steady state approach. Problem statement: The differences in characteristics between hydrogen and hydrocarbon fuels are led to the difference in the behavior of physical processes during engine cycle. One of these processes is the in-cylinder heat transfer. Approach: One … …American Journal of Environmental Sciences, Vol. 6, Issue 2 · 30 Apr 2010 · 7,428 accessesView PDFCite
