Evaluating Tunnel Safety and Ventilation With CFD

July 6, 2023 9:00 AM – 10:00 AM CDT

Understanding smoke propagation and temperature stratification in a tunnel during a fire incident is crucial to ensure the safety of tunnel users. Proper ventilation strategies must be employed to control the smoke propagation and allow for safe rescue and evacuation procedures. Computational fluid dynamics (CFD) simulations can provide valuable insight into the smoke and temperature behavior at a relatively low cost. However, CFD simulations of tunnel fires are challenging because fire dynamics are strongly transient and involve complex physics over a wide range of length scales. In this webinar, we’ll demonstrate the capability of CONVERGE CFD software to tackle this challenging problem with autonomous meshing, accurate combustion models, and robust conjugate heat transfer modeling. Together with Graz University of Technology, we’ll discuss how CONVERGE has been applied successfully to several tunnel projects.
