چکیده مقاله:
This paper consists on a three-dimensional numerical approach of natural convection in a cavity containing the nanofluid. The cavity contains an isothermal heating block in the middle of the bottom (case BH) and the top (case TH) walls and kept at a hot temperature TH. The right and the left vertical walls of the cavity are kept at a cold temperature Tc. The study's parameters are: the volume fraction Ф varying between ۰ and ۰.۰۳, and the Rayleigh number . The considered nanofluid is water + Cu. The results illustrate that the Rayleigh number Ra and the volume fraction Ф have a positive effect and they also improve the heat transfer. Interesting results have also been found while comparing the two considered configurations.
