Abstract

Convection and conduction in a fluid flow and a rigid body in contact with each other often occur in engineering situations, resulting in unsteady conjugate heat transfer (CHT). Although the analytical solutions to the separate conduction and convection issues are surprisingly straightforward, the combined conjugate heat transfer problem is substantially more complex to solve. This study investigates the CHT of a fluid (air) passing through an unbounded hemisphere. The hemisphere produces heat at a predictable and regular pace. The governing equations are solved using a finite volume system (FVS) using ANSYS Fluent V.16.0, with axisymmetric, no normal convection, and stable physical characteristics assumed. The findings showed The rise in air temperature will result in a more even dispersion of temperature.The temperature distribution will be narrowed as airflow velocity increases. Heat flow increases in the sphere, resulting in a greater temperature gradient over the object's surface.As airflow increases, so does the dispersion of flow rates. Increasing the pace of airflow will lead to an increase in air pressure distribution.
