This assignment consists of a problem that includes the main concepts of fire science, pre-flashover compartment fire dynamics and smoke management developed throughout the course. The problem solution is personalised for each student. The assignment consists of analysing the burning behaviour of a wood crib (fuel) when ignited in the open space. The burning of the crib is used as a fire scenario (heat release rate growth) to study the smoke filling of an atrium and the smoke extraction system to guarantee tenable conditions for occupants
