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 PDF Cite

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 PDF Cite

Research ArticleOpen accessIn the keywordsVariable 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 PDF Cite
