Nanoparticle Shapes Effects on Non-Darcy Mixed Convection from a Horizontal Plate Embedded in Water, Ethylene Glycol and Engine Based Cu, Al2O3 and SWCNTs Porous Media
Impact of nanoparticle shapes on non-Darcy mixed convection boundary layer flow over an impermeable horizontal flat plat embedded in a porous medium saturated by a nanofluid has been investigated. In distinctly most paramount studies, three types of nanoparticle shapes are employed into these studies namely sphere, cylinder and lamina. The controlling Partial Differential Equations are regenerated into a set of ordinary differential equations by manipulating similarity transformation and it is determined numerically by using Runge Kutta Fehlberg method with shooting technique from MAPLE 18. The surface of the plate is maintained at a constant temperature and constant nanoparticle volume fraction. Temperature profiles are graphically and tabular provided for the effects of mixed convection parameter, initial parameter, volume fraction parameter and empirical shape factor. The results show that solid volume fraction and nanoparticle shapes have powerful outputs in non-Darcy flow. Laminar nanoparticle shapes predicts a better results on heat transfer rather than other nanoparticle shapes.
