Resumen
The aim of the current study is to investigate the heat transfer performance of ????2??3 and ???? nanoparticles suspended based in ??2?? nanofluids inside a partially heated C-shaped enclosure. The governing equations for heat and flow transfer are solved using the Finite Element Method. Heat transmission is affected by the type and form of nanoparticles. To study the improved heat transfer performance, four different shapes of nanoparticles-spherical, cylindrical, column, and lamina-have been used. The investigation showed that among the considered shapes of nanoparticles, the lamina shape of nanoparticles performed best. Considering lamina nanoparticles, in comparison to the simple nanofluids ????2??3-??2?? and ????-??2?? the hybrid nanofluid ????2??3-????-??2?? provides the enhanced heat transfer rate. The heat transfer is governed by convection at a higher Rayleigh number. On the other hand, the heat transfer rate is decreasing by increasing the impact of the magnetic field. For the increased heat transfer rate, the best choice is lamina nanoparticles and hybrid nanofluid ????2??3-????-??2??.
