Özet
Buoyancy driven heat transfer of water-based CuO nanofluid in a tilted enclosure with a heat conducting solid circular cylinder on the center is studied numerically with Comsol Multiphysics modeling and simulation software. The upper and the bottom walls of the enclosure are kept in adiabatic conditions and the sidewalls of the enclosure are in isothermal conditions. The results show that nanoparticle usage enhances the heat transfer rate considerably. The results also show that average Nusselt number shows first an increase and then a decrease as the inclination angle is increased. The maximum heat transfer takes place at ?=45 deg for Ra=104 and at ?=30 deg for Ra=105 and 106. © 2012 Newswood Limited. All rights reserved.
