The problem of magnetohydrodynamic flow and heat transfer of a viscous, incompressible, and electrically conducting fluid past a semi-infinite unsteady stretching sheet is analyzed numerically. The problem was studied under the effects of Hall currents, variable viscosity, and variable thermal diffusivity. Using a similarity transformation, the governing fundamental equations are approximated b...

Rheological characteristics of Al2O3, CuO and TiO2 nano particles were investigated in oil asthe base fluid at 1 and 2 wt.%. Constitutive relations for non-Newtonian fluid were discussedbased on the power-law model. Measured viscosities of each nanofluid were used to evaluatethe power-law and consistency index. Results indicated that the nanofluid viscosity decreasedby increasing the concentrat...

This article looks at the Soret and Dufour effects on the magnetohydrodynamic (MHD) peristaltic flow of variable viscosity fluid in a symmetric channel. Analysis is presented in the presence of Ohmic heating. Results for the stream function, temperature and concentration are constructed. The variations of sundry parameters are analyzed.

We investigate the effects of variable viscosity and chemical reaction on mixed convection flow in a viscous fluid over a porous wedge. The governing boundary layer equations are resulted into dimensionless form using similarity transformation. The transformed second order equations are solved analytically. The effects of different parameters on the dimensionless concentration profiles are show...

This paper aims the study of electrically conducting Newtonian fluid flow and heat transfer considering slip at moving belt with temperature dependent viscosity. A domain decomposition method (ADM) is employed to solve non-linear system equations. Explicit expressions are obtained for velocity profile distribution. Effect variable viscosity parameter, slip, Hartmann number, Brinkmann number Sto...
