Research ArticleOpen accessEvery word in the titleModeling of Nitric Oxide Formation in Single Cylinder Direct Injection Diesel Engine Using Diesel-Water EmulsionK. Kannan, M. UdayakumarProblem statement: Water injection into the combustion chamber of diesel engine found to be one of best method for in-cylinder control of NOx formation. Approach: The combustion of water-diesel emulsion in diesel engine was simulated using a computer program to estimate the heat release rate, cylinder pressure, brake thermal efficiency, brake specific fuel consumption and NO formation. Results: The numerical … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 7,268 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFlow Simulation in Engine Cylinder with Spring MeshM.H. Shojaeefard, A.R. NoorpoorThis investigation presents results from numerical simulation of the air flow in Spark Ignition Engine (SI engine) cylinder. Accurate modeling of the flow in cylinder is a key part of successful combustion simulation. The most usual numerical method in Computational Fluid Dynamics (CFD) is finite volume. In this investigation an important, common fluid flow patterns in CFD simulations, namely, Tumble … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,061 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDevelopment of Dual Fuel Single Cylinder Natural Gas Engine an Analysis and Experimental Investigation for Performance and EmissionSyed Kaleemuddin, G. Amba Prasad RaoThe present study reports the experimental investigations carried and upgradation of 395 cc air cooled engine to dual fuel (CNG/Gasoline) application. The original 395 cc direct injection naturally aspirated, air cooled diesel engine was first converted to run on Gasoline by addition of electronic ignition system and reduction in compression ratio to suit both gasoline and CNG application. CFX software … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 7,768 accessesView PDFCite
Research ArticleOpen accessIn the keywordsContributions to the Stirling Engine StudyFlorian Ion Tiberiu PetrescuIn the process of transforming thermal energy into mechanical work, among the known thermal machines, the Stirling engine is the one that can achieve the highest yield (theoretically up to the maximum yield of the Carnot cycle), although in practice it is reduced by the properties of gas and materials used such as friction coefficient, thermal conductivity, melting point, breaking … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 4 · 22 Nov 2018 · 10,172 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMotor Oil Viscosity Stratification in Friction Units of Marine Diesel MotorsSergey Viktorovich Sagin, Oleksandr Vladymyrovich SemenovThe phenomenon of the motor oil viscosity stratification in lubricating the cylinder-piston units of marine diesel engines has been investigated. The correlations for determining the shear stress and the velocity, occurring in the liquid flow between the parallel planes, have been given. The modes of the hydrodynamic and the boundary lubrication, taking place in the cylinder assembly of the marine … …American Journal of Applied Sciences, Vol. 13, Issue 2 · 15 Feb 2016 · 8,011 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOperational Fault Diagnosis in Industrial Hydraulic Systems Through Modeling The Internal Leakage of its ComponentsP. Athanasatos, D. Koulocheris, T. Costopoulos, K. RaptisIn this study, a model of a high pressure hydraulic system was developed using the bond graph method to investigate the effect of the internal leakage of its main components (pump, cylinder and 4/2 way valve) on the operational characteristics of the system under various loads. All the main aspects of the hydraulic circuit (like the internal leakages, the compressibility … …American Journal of Applied Sciences, Vol. 10, Issue 12 · 7 Nov 2013 · 7,247 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFrictional Impact Modeling of a Cereal ThresherChristian Okechukwu OsuekeProblem statement: There is no point producing cereal threshing models that cannot replicate its performance on the field. The frictional impact that occurs between the crop surface and threshing cylinder had been often neglected by most researchers in cereal threshing. Approach: Study proffers a solution to this issue by developing a model for threshing which in-cooperate friction. This was done … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 3 · 29 Nov 2011 · 7,837 accessesView PDFCite
