Research ArticleOpen accessPhrase in the titleEffect of the Maximum Density Ratio Between Liquid and Vapor on Cavitating SimulationGuangjian Zhang, Weidong Shi, Ling Zhou, Desheng ZhangThe Filter-Based Model (FBM), which was built into CFX through CFX Expression Language (CEL) and a homogeneous cavitation model were employed to simulate cavitating flow around a 2D Clark-y hydrofoil. The effect of a maximum density ratio between liquid and vapor on sheet and cloud cavitating simulation was investigated. The results show that the maximum density ratio has a significant … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 21 Apr 2015 · 7,433 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Binary and Ternary Models in Powder Packing Density for Additive Manufacturing ApplicationsTaher M. Abu-Lebdeh, Oluwatobiloba Adetokunbo KalejaiyePowder packing is a very important aspect of additive manufacturing (3-D printing), as it directly impacts the final physical and mechanical properties of the printed objects. Improving the packing density of powder directly impacts the microstructure of the finished 3D-printed product, which also contributes to the surface finish. In order to achieve the densest packing for a powder, different sizes … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 2 · 15 Jun 2021 · 7,275 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Watershed Structures in Controlling Runoff - Case Study of Sardasht Basin in IRANSeyedeh Zahra Hosseini-Teshnizi, Ghodratollah Davoudi, Seyedeh Laleh Razavi, Kaveh Ostad-Ali-AskariIn order to investigate the performance of constructed structures in Sardasht watershed, Soil and Water Assessment Tools model for simulation of runoff and sediment during the studied period of 1996-2012 was carried out for two cases of existence and absence of flood control structures. From 2007 onwards by performing watershed operations in these sub-basins, the average runoff rate decreased about … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 1 · 26 Feb 2020 · 7,346 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Cement Chemistry on the Performance of Cement Stabilized Tropical Lateritic SoilOdumade Adegboyega Oduniyi, Ezeah Chukwunonye, Charles Nnamdi Ezugwu, Ekeoma EmmanuelChemical composition affects overall performance of cement on other materials such as when used in concrete or for stabilization of lateritic soil. This research studied the influence of chemical composition of three Portland cement types represented as samples A, B and C on engineering performance when mixed with laterite under tropical environmental conditions.The Lateritic soil sample classified according to AASHTO … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 21 May 2018 · 8,804 accessesView PDFCite
Research ArticleOpen accessIn the abstractWater Filter Fabrication from a Mixture of KMnO4 Modified Kapok Carbon Fiber, Zeolite, Bentonite and Clay for Fe3+Removal and Water Hardness TreatmentKannika Thongdee, Kalayaporn Parun, Suphakrit Benjatitmongkhon et al.A water filter was fabricated from a mixture of KMnO4 modified kapok carbon fiber, zeolite, bentonite and kaolinite clay for Fe3+ removal and water hardness treatment. The effects of amount of KMnO4 modified kapok carbon fiber (30-60 wt%), zeolite (20-40 wt%) and sintering temperature (500-700°C) on the properties of sintered products were evaluated. The best of sintered products were tested … …American Journal of Applied Sciences, Vol. 14, Issue 6 · 15 Jun 2017 · 7,580 accessesView PDFCite
Research ArticleOpen accessIn the abstractPREPARATION OF ACTIVATED CARBON FROM PALM OIL SHELL BY CHEMICAL ACTIVATION WITH Na2CO3 AND ZnCl2 AS IMPRENATED AGENTS FOR H2S ADSORPTIONKanokorn HussaroHydrogen Sulfide (H2S, rotten-egg) is one of the major environmental pollutants having its sources in natural and anthropogenic activities. It’s had smell gas produced by anaerobic digestion in acid condition from organic and inorganic compounds containing sulphur, presents dual problems of its toxicity and foul ordour. One of methods of its removal is adsorption. Activated carbon is a widely used … …American Journal of Environmental Sciences, Vol. 10, Issue 4 · 17 Jun 2014 · 8,480 accessesView PDFCite
Research ArticleOpen accessIn the abstractHypolipidemic Effects of Coenzyme Q10 in Experimentally Induced Hypercholesterolemic Model in Female RatsAtef M. Al-AttarProblem statement: Hyperlipidemia is well known to play a main role in the development of atherosclerosis. It is characterized by abnormally elevated cholesterol, triglyceride, low density lipoprotein cholesterol and very low density lipoprotein cholesterol levels in the blood. It has been recognized for many years that hypercholesterolemia is a major risk factor for cardiovascular diseases such as atherosclerosis, myocardial infraction, … …American Journal of Pharmacology and Toxicology, Vol. 5, Issue 1 · 31 Mar 2010 · 45,646 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentification of Shear Band using Elastic Shear Wave PropagationT. Nachiengtai, W. Chim-Oye, S. Teachavorasinskun, W. Sa-NgiamviboolLocalization in soil under high stress level is usually investigated using some indirect measures, e.g., X-ray diffraction method. In the present study, the propagation velocity of shear wave was used to detect localization in sandy soil. Firstly, the general expression to exhibit the stress and density dependencies characteristics under consolidation and triaxial testing conditions of the tested soil was proposed. … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2008 · 6,794 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhysical Characteristics of Maize Cob Briquette under Moderate Die PressurePatomsok WilaiponThe potential energy content of maize cob available in Thailand was calculated based on maize productivity, the residue-to-product ratio and the heating value of maize cob. It was found that the computed value was about 74.2 PJ/year. Besides, the potential energy value exceed 1,000 TJ/year was also reported for the case of five provinces of Thailand. Concerning with maize cob … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 8,087 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordREMOVAL OF HIGH DENSITY IMPULSE NOISE USING MORPHOLOGICAL BASED ADAPTIVE UNSYMMETRICAL TRIMMED MID-POINT FILTERS. Saravanakumar, A. Ebenezer Jeyakumar, K. N. VijeyakumarA Morphological based Adaptive Unsymmetrical Trimmed Mid-Point Filter (MAUTMPF) for the restoration of gray scale images corrupted by salt and pepper noise for varying noise densities is proposed in this study. Images corrupted by impulsive noise severely hinder subsequent image processing tasks, such as edge detection, image segmentation, object recognition, etc. Therefore, it is absolutely essential to restore the original … …Journal of Computer Science, Vol. 10, Issue 7 · 17 Jun 2014 · 6,543 accessesView PDFCite
