报告摘要: Recent wildland fires have shown once again the dramatic impact on the environment and society these events can have. Therefore, it is vital to better understand the dynamics of wildland fire spread to mitigate their effects. Models based on Computational Fluid Dynamics (CFD) have been developed and improved to provide a detailed description of wildland fire spread and their impact on structures, people and the environment. However, a robust understanding of the processes (i.e. fuel degradation, drag forces, convective heat transfer, and radiation) driving fire spread is still missing that efficiently transfer small scale effects to large scale fire brehavior. This talk will focus on detailing the challenges and opportunities related to CFD wildland fire spread models and how they can be improved. The wildland fire context will be first presented, then the modeling approach will be detailed along with the needs and challenges of capturing the physical processes involved in wildland fire spread. Then, several sub-models related to different processes will be presented with the approaches used to derive or improve them. Finally, some experimental activities in the field will be presented as they represent the baseline for validation of the dynamic aspect of the model.
报告人简介: Professor Albert Simeoni is the Department Head of Fire Protection Engineering at Worcester Polytechnic Institute (WPI) in Worcester, Massachusetts. He is an internationally recognized leader in fire science with over 120 journal papers, conference papers, and book chapters. He has more than 20 years of experience developing experimental, analytical, and numerical techniques to better understand fire dynamics and to predict fire and wildland fire behavior. Before joining WPI, he held academic leadership positions in fire research in the UK (university of Edinburgh) and in France (university of Corsica). He has also experience as a consultant in fire science in the US and has spent over 10 years volunteering and working as a firefighter in France. Starting as a volunteer firefighter, he ultimately led all aspects of fire, wildland fire, and rescue operations, in the capacity of Chief of Fire Station.
