The present study develops a numerical model of conjugate heat transfer between a fluid and a solid, which is essential for the optimization of engineering systems such as heat exchangers, electronic cooling systems, and industrial reactors. The simulation is performed using ANSYS Fluent, where heat transfer in both domains and at their shared interface is analysed.
The modelling procedure includes mesh generation, definition of physical models and material properties, as well as specification of boundary conditions for temperature and fluid velocity. The governing equations of mass, momentum, and energy conservation are solved, with automatic coupling of temperature and heat flux at the fluid–solid interface. The obtained results provide temperature and heat flux distributions, enabling quantitative evaluation of heat transfer efficiency and identification of critical thermal regions.
