Abstract
This paper examines numerically the thermal and flow field characteristics of the laminar steady natural convection flow in a square enclosure filled with hybrid nanofluid with two heater and cooler sources with random temperature (based on the random function) embedded within, walls of the cavity are considered adiabatic. The fluid inside the enclosure is a water based hybrid nanofluid containing different types of solid spherical nanoparticles (Ag and Ag-TiO2). Based on the numerical results, the effect of the dominant parameters such as; volume fraction of nanoparticles (φ=0.025, 0.1), types of temperature (constant, random) and types of ((Ag or Ag-TiO2)-water) are examined using the finite volume method.Comparisons with previously numerical works are performed and good agreements between the results are observed. It is found that nanoparticles addition remarkably enhances heat transfer in the cavity for (φ=0.1). Besides, the effect of temperature’s type is more pronounced at higher Rayleigh number.
