Abstract
This study presents the results of a numerical simulation of fluid flow within a chamber bounded by a horizontal, flat wall heated at a constant flow rate and an upper wall with an elliptical outline. The results of this simulation enable the implementation of a cooling system utilising natural convection. The key parameters in this study are dimensionless numbers such as the Rayleigh number and the Nusselt number, which characterise the magnitude of heat transfer by convection. To determine the thermal parameters of the problem, we shall use the heat equation and the equation of motion in our modelling. To obtain results such as the average temperature characterising heat transfer between the fluid and the wall, and the Nusselt number indicating the efficiency of convective cooling, we will solve the non-linear equations using the finite volume method and the Gauss-Siedal iterative method.
This study presents a numerical investigation of natural convection in a two-dimensional inclined square cavity filled with air and subjected to differential heating. The effects of the Rayleigh number and cavity inclination on heat transfer and flow behavior were investigated for 103 ≤ Ra ≤ 109 and inclination angles...

The purpose of this research is the analytical solution of unsteady natural convective flow of a viscous incompressible fluid, which flows over an isothermally heated infinite vertical cylinder. Uniform magnetic field is applied in the direction perpendicular to the cylinder and normal to the direction of the flow. Con...
