Abstract
The present study investigates the influence of temperature dependent viscosity on dynamics of pressure driven nanofluid flow over a curved surface. A uniform applied magnetic field perpendicular to the surface is taken into consideration. Governing nonlinear partial differential equations are modeled with the help of boundary layer approximation. Suitable similarity transformations are used to convert governing equations into nonlinear ordinary differential equations. These highly nonlinear ordinary differential equations are then solved with the help of a second order implicit finite difference scheme. Graphical and numerical results depict the impact of temperature sensitive viscosity and other physical parameters on flow of nanofluid. Viscosity parameter evidently resist the flow velocity and rise the temperature distribution in the nanofluid. It also increases the Skin friction near the boundary of the fluid.
