ABSTRACT
This study employs finite element modelling to investigate convective heat transfer in underground tunnels, a crucial aspect of tunnel design and safety. The developed model simulates coupled heat transfer model, fluid flow and thermal radiation, considering non-linear material properties and turbulent flow. The results reveal complex heat transfer patterns and fluid flow dynamics, emphasizing the importance of accurate modelling for efficient tunnel design and operation.
The finite element approach enables parametric studies, sensitivity analysis and optimization of tunnel geometry, lining materials and ventilation systems. This enables the identification of optimal designs configurations that enhance thermal comfort, energy efficiency and safety in underground infrastructure.
This research contributes to the development of advanced numerical tools for tunnel designs, supporting the creation of sustainable and safe underground tunnels. The findings have significant implications for the optimization of tunnel designs, ventilation system and energy efficiency, ultimately reducing energy consumption and environmental impact.
