原始语种摘要: Abstract(#br)A numerical investigation of hydrodynamic and heat transfer behaviors for Al 2 O 3 –water nanofluids for laminar confined slot jet impingement is presented. This study has been conducted by considering the nanofluid as Newtonian as well as non-Newtonian for a wide range of solid volume fraction (0 ≤ φ ≤ 5 %) and Reynolds number range of (25 to 300). A single-phase fluid approach was used to model the nanofluid and the Ostwald–de Waele model described the non- Newtonian shear thinning nanofluid behaviour has been adopted. A comparison with Newtonian and non-Newtonian nanofluid in terms of heat transfer coefficient, Nusselt number, streamlines and isotherms contours has been performed for the same Reynolds number, jet inlet velocity and the same aspect ratio H/W . It has been...
