Abstract

The phenomenon of heat transfer is scrutinized in the nanofluid flow problem by suspending Copper and Aluminium oxide nanoparticle with base fluid as water. The flow takes place over a stretching sheet along with the presence of nonlinear thermal radiation. The governing equations are simplified into ordinary differential equations with the help of bunch of similarity transformation. Reduced equations are solved numerically using Runge Kutta Fehlberg fourth fifth order technique. The influence of related parameters and their physical resultant interpretation are presented and discussed in detail with the help of graphical representation. It is reported that, the heat transfer augmentation is more for platelet shape nanoparticle than cylindrical shape. Moreover, heat transfer phenomena are more significant for nonlinear thermal radiation.
