Impacts of different shapes of nanoparticles on SiO₂ nanofluid flow and heat transfer in a liquid film over a stretching sheet

The present study manipulates the unsteady film flow and heat transfer of SiO ₂ water nanofluid over a stretching sheet under convective boundary conditions. Governing partial differential equations (PDEs) are transformed into a set of nonlinear ordinary differential equations (ODEs) and then solved using BVP4C in MATLAB. The impact of multi-shape SiO ₂ nanoparticles along with other pertinent parameters, such as Prandlt, Eckert and biot-number on flow and heat transfer characteristics is examined via graphical simulations. Moreover, the skin-friction coefficient and Nusselt number are also computed and tabulated, numerically. The study reveals that platelet shape of SiO ₂ nanoparticles possess the high flow and heat transfer rate. In addition, temperature profile enhances by augmenting volume-fraction parameter and biot-number but the reverse trend is found for slip parameter. (paper)
