Mitigating toxic gases leaking during excavations in infrastructure projects is crucial for both human health and environmental protection. In this context, Computational Fluid Dynamics (CFD) simulations are highly valuable for modeling and analyzing the complex physical processes related to the transport and dispersion of gases. During infrastructure projects in geothermal regions, various gases may leak from underground sources. These gases may include toxic and/or flammable substances such as hydrogen sulfide (H₂S), carbon dioxide (CO₂), and methane (CH₄). Designing an effective ventilation system is essential to mitigate toxic gases through ventilation. CFD simulations can be utilized to evaluate the design and performance of ventilation systems. Modeling gas leaks from sources encountered during excavations with CFD simulations can help understand how these gases move throughout infrastructure projects and assess their environmental impacts. CFD simulations assist in optimizing factors such as the placement of ventilation systems, duct design, airflow velocities, and filtration efficiency. This optimization ensures the effective removal of toxic gases and minimizes environmental impacts. Moreover, CFD simulations can be used to evaluate the efficiency and safety of ventilation systems in mitigating toxic gases. Simulating the operation of ventilation systems during potential emergency scenarios can also aid in risk assessment and preparedness..
