Abstract

In this study, a numerical investigation of natural convection heat transfer of hybrid nanofluid inside a Γ-shaped enclosure is studied. The fluid flows under steady, laminar, and incompressible conditions. The simulation of flow is done for two dimensions x and y respectively. Water- Alumina- Copper hybrid nanofluid is the fluid used in this study with the base fluid taken to be water (H_2 O) and the nanoparticles are Alumina (Al_2 O_3) and Copper (Cu). The upper right vertical wall is kept at T_c .As for the lower right vertical and horizontal wall, they are kept at T_h. The top and bottom walls are adiabatic. The governing partial differential equations which are Navier Stokes equations as well as Energy equation are approximated and solved numerically using the finite difference method utilizing Mathematica 10 software. The streamlines and isotherms are illustrated graphically against the varied Grashof number as well as the nanoparticles volume fraction.
