Research ArticleOpen accessIn the abstractNumerically Studying the Effect of Stiffening Rings on Reducing the Thickness of Torospherical Heads under Pressure on Their Concave SideSa'id Golabi, Ali Ghorbanpour-Arani, Arash ZamaniThe high thickness of heads used in pressure vessels is always one of the main concerns of designers and manufacturers. A thorough study has been conducted on all types of heads including torospherical heads, with external and internal pressure to reduce their thickness using stiffening rings by finite element technique. Here the result of analysis on heads with pressure on … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 7,146 accessesView PDFCite
Research ArticleOpen accessIn the abstractDissolution Sintering Technique to Create Porous Copper with Sodium Chloride Using Polyvinyl Alcohol Solution through Powder MetallurgyCynthia Waters, Stephen Ajinola, Mustafa SalihThe main purpose of this paper was to investigate the relative densities, porosities, compression strength and energy absorbed by porous copper (Cu) formed via the dissolution sintering technique using Polyvinyl Alcohol (PVA) solution as a binder with Sodium Chloride (NaCl) as space holder. Porous Cu was fabricated through powder metallurgy route using dissolution sintering technique by mixing Cu with NaCl … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 13 Mar 2016 · 8,985 accessesView PDFCite
Research ArticleOpen accessIn the abstractFlattening Effect on Heat Transfer Characteristics of a Sintered-Wick Heat PipeWeeranut Intagun, Pradit Terdtoon, Phurt SakulchangsatjataiThe effect of pipe flattening on heat transfer characteristics and the internal phenomena of a sintered-wick heat pipe has been investigated by using three-dimensional Finite Element Method. The calculation domains were focused at three important regions, i.e., vapor core, wick and wall. The Cartesian coordinates and the three-dimensional tetrahedral elements were applied in this model. The selected total elements were … …American Journal of Applied Sciences, Vol. 10, Issue 7 · 4 Jul 2013 · 7,342 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Quasi Delay Insensitive Reduced Stack Pre-Charged Half Buffer based High Speed Adder using pipeline templates for Asynchronous CircuitsD. Jayanthi, M. RajaramProblem statement: Recent research in asynchronous design technique is making asynchronous circuits an increasingly practical alternative. These challenges include the increasing pressure for low power, the growing challenges of predicting the increasing impact of wire load and delay and the performance penalty associated with supporting communication between different clock domains Asynchronous is binary signals, but there is no common or … …Journal of Computer Science, Vol. 8, Issue 7 · 7 Jun 2012 · 7,078 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Simplified Analytical Modeling of the Hole Erosion TestMohammed Bezzazi, Abdellatif Khamlichi, Miguel Prron Vera et al.Problem statement: Internal erosion occurs in soils containing fine particles under the action of high pressure gradients that could result from water discharge. This phenomenon can yield in its final stage to the formation of piping which constitutes a real threat for hydraulics infrastructures as it can precipitate their entire rupture in very short time. In order to mitigate this … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 30 Nov 2010 · 8,025 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Wall Roughness and Concentration of Clay on Erosion in the Hole Erosion TestKissi Benaissa, Parron Vera Miguel Angel, Rubio Cintas Maria Dolores et al.Problem statement: Internal soil erosion is a real threat for hydraulic infrastructures. In its final stage it develops in piping involving the formation and progression of a continuous void inside the soil between the upstream and downstream sides. The hole erosion test was introduced to characterize kinematics of piping in terms of the time left to rupture. Actual modeling approaches … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 22 Nov 2010 · 8,506 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
