Research ArticleOpen accessPhrase in the titleDevelopment of a Magnetorheological Finishing Machine for Small-Bore Part of Irregular Shape and Experimental StudyWang Tingzhang, Chen Mingjun, Liu Henan, Xu JiangMagnetorheological finishing machine tool with small ball-end permanent-magnet polishing head is proposed as a method to solve the problem that small-bore parts of irregular shape with small curvature radius concave surface cannot be polished by traditional magnetorheological finishing machine tool. The four-axis linkage magnetorheological finishing machine tool with modular open numerical system and easy-operating man-machine interactive interface is developed. Then … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 3 · 26 Jun 2015 · 7,693 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleExperimental Study of Flow Structures of Circular Pulsating Air JetRozli Zulkifli, Kamaruzzaman Sopian, Shahrir Abdullah, Mohd Sobri TakriffProblem Statement: Applications of impingement jets in industry for heating and cooling purposes requires a high convective heat transfer coefficient. Numerous studies have been conducted to improve the convective heat transfer coefficient for a steady impinging jet. A pulsating jet has a very high potential in replacing steady jet after it been found able to increase the heat transfer coefficients … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 7,778 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleAN EXPERIMENTAL STUDY ON HEAT TRANSPORT CAPABILITY OF A TWO PHASE THERMOSYPHON CHARGED WITH DIFFERENT WORKING FLUIDSM. Kannan, R. Senthil, R. Baskaran, B. DeepanrajIn the present investigation a two phase thermosyphon has been fabricated to investigate the effect of operating parameters on the heat transport capability. The system consists of evaporator section, adiabatic section and condenser section with thermocouples located on the wall of thermosyphon. Electric heater was fixed on the bottom of the evaporator section and water jacket for cooling the condenser … …American Journal of Applied Sciences, Vol. 11, Issue 4 · 1 Feb 2014 · 6,524 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleExperimental Study of Near Wake Flow Behind a Rectangular CylinderAbdollah Shadaram, Mahdi Azimi Fard, Noorallah RostamyThe turbulence characteristics of the near wake flow behind a rectangular cylinder is investigated in a two-dimensional analysis using a hot-wire anemometer. The time-averaged and fluctuating components of the velocity are measured for a cylinder having various width-to-height (b h-1) ratios. The measurements are carried out in a low-speed wind tunnel. Data from hot-wire anemometer is collected by a data … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 7,270 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleThe Influence of the Climatic Factors on the Decay of Marbles: an Experimental StudyPaola Marini, Rossana BellopedeStone decay is affected by the influence of climatic factors. In particular marble degradation, that could be expressed by decohesion and /or bowing, is mainly due to the action of temperature and water (rains and relative humidity). In this work non destructive and destructive tests have been performed to evaluate the decay of marble slabs subjected both to natural exposition … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 7,123 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleAn Experimental Study of Petty Corrupt Behaviour in Small Decision Making ProblemsTakemi FujikawaThis research discusses small decision making problems and petty corruption as their practical applications with a structured economic experiment. One of examples of petty corruption considered includes demands for petty bribes by traffic officials followed by police. We examine that it is caused by subjective underweighting of rare events and its objective probabilities. This literature reports results of an experiment, … …American Journal of Applied Sciences, Vol. 2, Issue 13 · 3 Dec 2005 · 8,105 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleExperimental Study of Parameters Influencing the Purity of Potassium Sulfate Fertilizer Produced from Jordanian Raw MaterialsMousa GougazehThe general objective of the present investigation was to make a contribution towards improving the purity of the produced potassium sulfate from (KCl, Arab Potash Company-Dead Sea) and (H2SO4, Jordanian Phosphate Company). The process parameters influencing the contamination of the poisoning chlorine within the product were experimentally investigated. The experiments were performed in a small-scale batch reactor equipped with a … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 7,042 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleExperimental and Skeletal Kinetic Model Study of Compressed Natural Gas Fueled Homogeneous Charge Compression Ignition EngineP. M. Diaz, B. Durga Prasad, D.S. Manoj Abraham, K. PalaniKumarProblem statement: In homogeneous charge compression ignition engines fuel oxidation chemistry determines the auto-ignition timing, heat release, reaction intermediates and the ultimate products of combustion. To shorten development time and to understand combustion processes, the use of simulation is increasing. Approach: A model that correctly simulates fuel oxidation at these conditions would be a useful design tool. Detailed models of … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 22 Mar 2012 · 7,255 accessesView PDFCite
