چکیده

Heat transfer in a symmetrical cavity with two semi-cylinders was explored this study. Several parameters, such as (103?Ra?106), (10?5?Da?10?2), (0.02???0.08), (0.2???0.8), and (0?Ha?100) were selected evaluated research. The outcome of the magnetic field temperature gradient on nanofluid flow is considered. geometric model therefore described using symmetry technique. issue for governing equations has been solved Galerkin finite element method (G-FEM), these solutions are presented dimensionless form. energy, motion, continuity application COMSOL Multiphysics® software computer package. According to results, there difference occurrence parameter an increase heat transmission when right wall recessed inward. also significantly reduced exposed outside. number Nusselt grows directly proportional nanofluids environment. In contrast, all porous media low Darcy Hartmann numbers, high porosity, volume fraction have numbers. It found that double streamlines hot side single cooling Darcy, Rayleigh, A cold isotherm at various physical parameters needed top cavity. Rayleigh’s solid raise Darcy’s number, increasing inside thermal entropy determines components.

Entropy Generation and Natural Convection of CuO-Water Nanofluid in C-Shaped Cavity under Magnetic Field

This paper investigates the entropy generation and natural convection inside a C-shaped cavity filled with CuO-water nanofluid and subjected to a uniform magnetic field. The Brownian motion effect is considered in predicting the nanofluid properties. The governing equations are solved using the finite volume method with the SIMPLE (Semi-Implicit Method for Pressure Linked Equations) algorithm. ...
