Impact of nanoparticle shape on aligned MHD free convection flow of hybrid nanofluid over a vertical plate with convective boundary condition / Nur Hazimah Basir

This study conducted to investigate the impact of nanoparticles' shape on the thermal conductivity behavior of hybrid nanofluid. It focused on the effect of six different physical conditions on velocity and temperature profile as well as the value of skin friction and Nusselt number. There are five nanoparticles shape involved in this study which are spherical, bricks, cylindrical, platelet, and blade. This study applied numerical approach and method used is Forth-Order Runge Kutta numerical method. Similarity transformation was used to reduce the non-dimensionless partial differential equations in the form of dimensionless ordinary differential equation. The results obtained by the study indicates that the blade shape is high in thermal boundary layer thickness and high in thermal conductivity since the temperature profile of the hybrid nano fluid is high. Meanwhile, the spherical shape temperature profile is the lowest which means that the hybrid nanofluid with the shape of the spherical nanoparticle has less thermal boundary layer thickness and its thermal conductivity is low. Besides that, the results also show that the blade shape has the highest skin friction and Nusselt number compared to the other nanoparticles' shape. All in all, the shape of the nanoparticles can affect the behavior of nanofluid.
