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 105-107. The results show that temperature inside the enclosure decreases considerably when nanoparticles are used in the cylindrical electronic control. The results also show that temperature inside the enclosure decreases substantially with an increase in the Rayleigh number.eninfo:eu-repo/semantics/closedAccessAl 2o 3; Cylinder; Nanofluid; Natural Convection; Nusselt Number; Rayleigh NumberBoussinesq Approximations; Computational Results; Control Unit; Cylindrical Enclosure; Electronic Controls; Governing Equations; Injection Wells; Multi-Physics; Nano-Fluid; Rayleigh Number; Solid Volume Fraction; Aerodynamics; Aluminum; Computer Software; Control; Cylinders (Shapes); Enclosures; Finite Element Method; Fluid Mechanics; Fluids; Hydrocarbons; Injection (Oil Wells); Mass Transfer; Nanoparticles; Natural Convection; Nusselt Number; Oil Wells; Silicones; Wells; NanofluidicsConference Object1581632-s2.0-83655181716N/A
