This study is aimed at characterizing the dynamics of
compartment fires under poorly ventilated conditions.
The study considers four cases that correspond to
different values of the fire room global equivalence
ratio and are representative of strikingly different
flame behaviors. The study is based on a detailed
comparison between experimental and computational data.
The numerical simulations are performed with the Fire
Dynamics Simulator (FDS) developed by the National
Institute of Standards and Technology, USA. The
comparative tests serve to evaluate the general ability
of FDS to describe the transition from over- to
under-ventilated fire conditions, as well as the
transition from extinction-free conditions to conditions
in which the flame experiences partial or total
