The governing equations obtained with the Boussinesq approximation are solved using Comsol Multiphysics finite element analysis and simulation software. Computational results are obtained for nanoparticle solid volume fraction in the range of 0%-8% and for Rayleigh number in the range of 10 5-10 7. The results show that heat transfer rate increases considerably when nanoparticles are used in the cylindrical enclosure. The results also show that heat transfer rate increases substantially with an increase in the Rayleigh number.eninfo:eu-repo/semantics/closedAccessCuo; Cylinder; Nanofluid; Natural Convection; Nusselt Number; Rayleigh NumberBoussinesq Approximations; Computational Results; Concentric Cylinders; Cuo; Cuo Nanofluid; Cylindrical Enclosure; Governing Equations; Heat Transfer Rate; Multi-Physics; Nano-Fluid; Rayleigh Number; Solid Volume Fraction; Water Based; Aerodynamics; Computer Software; Cylinders (Shapes); Finite Element Method; Fluid Mechanics; Fluids; Mass Transfer; Nanoparticles; Natural Convection; Nusselt Number; Specific Heat; NanofluidicsConference Object1641692-s2.0-83655212183N/A
