Towards a Sustainable Future: The Role of CFD in Innovating Indoor Environmental Quality and Energy Systems

This doctoral dissertation addresses critical 21st-century challenges by integrating experimental and Computational Fluid Dynamics (CFD) approaches to enhance sustainability, indoor air quality (IAQ), and energy efficiency. Part I focuses on decarbonization strategies in Waste-to-Energy (WtE) plants, leveraging CFD models to optimize combustion conditions and reduce harmful emissions. Part II examines IAQ through advanced CFD modeling and experimental studies, including respiratory particle transport and infection risk in close-contact and large indoor settings. Part III applies these findings to evaluate protective devices and HVAC system impacts, offering innovative solutions for healthier indoor environments and energy-efficient designs.
