NUMERICAL INVESTIGATION OF MIXED CONVECTION OF SiO2-WATER NANOFLUIDS WITHIN AN INCLINED DOUBLE LIDS-DRIVEN CAVITY

摘要
To investigate mixed convection flows through nanofluid in a square double lid-driven cavity with various inclination angles, a numerical method based on the finite volume approach was applied. In this study, a SiO2-water nanofluid was used. The cavity was nonuniformly heated from the left, Th, and cooled from the opposite wall. The top and the bottom moving walls were insulated. The study was conducted for the Richardson number 0.1 to 10, Reynolds number 1 to 100, with solid volume fractions (φ) of nanoparticles being altered from 0 to 0.06. The Patel and Brinkman models were used for calculating thermal conductivity and effective viscosity of the nanofluid, respectively. The impact of Reynolds number, Richardson number, inclination of cavity, and of solid volume fraction of the nanofluid on the hydrodynamic and thermal characteristics were studied and discussed. As a result, it was found that the heat transfer rate increases with solid volume fraction.
