The governing equations of continuity, momentum and energy are transformed into nonlinear ordinary differential equations using similarity transformations and then solved by using the Runge-Kutta-Gill method along with shooting technique. Governing parameters for the problem under study are the variable viscosity, thermal stratification parameter, non-Newtonian parameter and the power-law index parameter.The velocity and temperature distributions are presented and discussed. The Nusselt number is also derived and discussed numerically.}, type={Artykuły / Articles}, title={Effect of variable viscosity on free flow of non-Newtonian power-law fluids along a vertical surface with thermal stratification}, URL={http://journals.pan.pl/Content/94380/PDF/06_paper.pdf}, doi={10.2478/v10173-012-0030-z}, keywords={Free convection, Thermal stratification, Non-Newtonian, Variable viscosity, Porous medium}, }
