GRAPHENE-BASED NEWTONIAN NANOLIQUID FLOWS OVER AN INCLINED PERMEABLE MOVING CYLINDER DUE TO THERMAL STRATIFICATION

ABSTRACT
Heat flux enhancement due to utilization of graphene, graphene nanoplatelets, and graphene oxides in water/ethylene-glycol based nanofluids over an inclined permeable cylinder is focused in the present study. The governing PDE are reformulated into non-linear ODE by applying similarity expressions. A shooting procedure is opted to reformulate the equations into boundary value problems which are solved by employing a numerical finite difference code in MATLAB. The effects of constructive parameters toward the model on non-dimensional velocity and temperature dissemination, reduced skin friction coefficient and reduced Nusselt number are graphically reported and discussed in details. It is observed that by in-creasing the thermal stratification and inclination angle, the temperature profile and Nusselt number for the selected nanofluids will be decreased.
