IAFSS 9th Fire Spread Modeling Workshop

Nicholas A Dembsey (WPI) and Simo Hostikka (VTT)

Fire Spread Modeling in the CFD Era: the needed fundamentals and engineering concerns

This workshop will focus on two key aspects of this important area in the context of modern fire modeling (CFD based). The fundamentals discussion will be focused on improving engineering tools based on sound science. Common engineering concerns will be addressed focusing on model parameter estimation in the context of practical fire scenarios.

A distinguished panel of international experts will lead discussions in the below noted areas. Each discussion will start with an informal presentation by a panelist to provide general context. The organization of the workshop is such that significant time will be allotted for group discussions allowing workshop participants ample opportunity to share their expertise and experience with the group.
