Abstract
This study explains the result of natural steady convection that originates from a heated cylinder within an inclined enclosure. The convection processes occurring due to the temperature differences among the heated cylinder, heated walls, and the cold walls of the enclosure were investigated using different dimensionless numbers (Grashof and Prandtl numbers). The Grashof and Prandtl numbers span from 10 to 104 and 0.7 to 90 respectively. A numerical solution to the governing partial differential equations was obtained. The intricate flow patterns visibly represented by the streamlined contours when Prandtl and Grashof numbers were applied. Convection currents could be found around the heated inner cylinder, demonstrating how buoyancy-driven forces played a pivotal role in shaping the circulation in the annular space. Isotherm contours illustrate thermal gradients and the impact of buoyancy-induced flow. The local Nusselt number distribution can be used to determine the various contributions made by dimensionless numbers to the heat transfer rate. Data are often displayed using variations in the average Nusselt values on the cylinder surface. The local Nusselt number was used to find out how much convective heat transfer occurred at a specific location on a surface compared to conductive heat transfer. Heat transfer outcomes can now be predicted in a new application because they have been observed as a function of Grashof and Prandtl numbers.
