Research ArticleOpen accessEvery word in the titleRarefied Gas Flow Modeling inside Rotating Circular CylinderN. PourmahmoudIn this study a rarefied gas flow inside a rotating circular cylinder by means of direct simulation Monte Carlo (DSMC) method is investigated. A rarefied gas is supposed to be contained in a cylindrical domain, bonded by a rotational cylinder with smooth and diffuse-reflection surface. The top and bottom ends of domain is assumed to be speculary-reflecting. Special attention is … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2008 · 7,451 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSomething about the Balancing of Thermal MotorsRaffaella Aversa, Relly Victoria V. Petrescu, Bilal Akash et al.Internal combustion engines in line (regardless of whether the work in four-stroke engines and two-stroke engines Otto cycle engines, diesel and Lenoir) are, in general, the most used. Their problem of balancing is extremely important for their operation is correct. There are two possible types of balancing: Static and dynamic balance. The total static to make sure that the sum … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 15 Mar 2017 · 7,785 accessesView PDF Cite

Research ArticleOpen accessIn the abstractExperimental 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 PDF Cite

Research ArticleOpen accessIn the abstractCorrosion of Copper Metal in Presence of Binary MixturesMedhat A. Shaker, Hanaa H. Abdel-RahmanThe rates of copper corrosion were determined in presence and in absence of different compositions of water-ethanol, -ethylene glycol, -glycerol, -dimethyl sulfoxide (DMSO) and -dioxane binary mixtures. The rates of corrosion were found to decrease by increasing the concentration of solvents. The percent inhibition range from 10.9 to 78.2% depends on the nature of solvent and its concentration. The calculated … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 8,230 accessesView PDF Cite
