Research ArticleOpen accessEvery word in the titleDetermination of Dynamic Viscosity of Viscous Oils using Mach Zehnder Digital Holographic MethodRittirong Nuansri, Pichet Limsuwan, Prathan BuranasiriThe digital in-line holography based on Mach Zehnder interferometer (MZDIH) was setup for the determination of dynamic viscosity of the viscous oils. The spherical irons were used as the falling objects in the viscous oils. The hologram images of the iron falling along its entire path were recoded as a video file on the CMOS camera. The recorded hologram images … …American Journal of Applied Sciences, Vol. 15, Issue 6 · 28 Jul 2018 · 7,687 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMotor 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 accessEvery word in the titleVariable Viscosity, Chemical Reaction and Thermal Stratification Effects on Mixed Convection Heat and Mass Transfer along a Semi-Infinite Vertical PlateP. Geetha, M.B.K. MoorthyProblem statement: In this research the researchers studied and made an analysis to the heat and mass transfer characteristics in a viscous fluid over a semi-infinite vertical porous plate by taking into account the variable viscosity, chemical reaction and thermal stratification effects. Approach: The governing partial differential equations were transformed into a set of coupled non-linear ordinary differential equations, which … …American Journal of Applied Sciences, Vol. 8, Issue 6 · 13 Jun 2011 · 6,848 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBoundary Effect on Marangoni Convection in a Variable Viscosity Fluid LayerN.Z. Abidin, N.M. Arifin, M.S.M. NooraniThe onset of Marangoni convection in a horizontal fluid layer with a free surface overlying a solid layer heated from below is studied. Problem is focused on the effect of the solid layer depth or its conductivity. The viscosity group, Rv, Biot number, Bi, depth ratio, dr and conductivity ratio, kr, are significant on determining the critical Marangoni number Mc … …Journal of Mathematics and Statistics, Vol. 4, Issue 1 · 31 Mar 2008 · 6,915 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleON SOLUTIONS IN THE HYDRODYNAMIC APPROXIMATION OF SOLAR AND STELLAR WINDS WITH VISCOSITYPanagiotis N. Koumantos, Panaiotis K. Pavlakos, Xenophon D. MoussasIn this article we present some results in existence and uniqueness of strong and classical solutions of the hydrodynamic equations modeling solar and stellar winds. The system of Navier-Stokes equations for solar and stellar winds is considered in its corresponding differential evolution equation form (d/dt+A)υ(t) = F(υ(t), t), where F is a given non-linear function and -A is the infinitesimal … …Physics International, Vol. 5, Issue 2 · 30 May 2014 · 7,553 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Effects of Using Crumb Rubber Modified Binder in an Asphalt PavementSayed Mohamad Soleimani, Alanoud Faheiman, Zainab MowazeIn this study, laboratory investigations have been carried out to characterize and demonstrate the improved performance of asphalt after modifying it with crumb rubber. The study has been divided into two main parts. Firstly, the physical characterizations of crumb rubber modified bitumen with different percentages of crumb rubber have been evaluated using penetration, softening point, viscosity, ductility and thin film … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 2 · 14 May 2020 · 8,377 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPreparation of Magnetorheological Fluids Using Different Carriers and Detailed Study on Their PropertiesVikram G. Kamble, Shreedhar Kolekar, Chetan MadivalarHigh sensitive and intelligence are the main function of the Magneto Rheological Fluids (MRF).
