Abstract

It is known that the main cause of death in residential fires is the combustion products ( ″smoke″ ) which spread and accumulate throughout the house. Therefore, in order to evaluate and improve the safety of a residence, it is essential to understand and predict the movement of those products. A tractable combined fluid mechanics and statistical solution is presented here for that purpose, resulting in the stress level function, caused by a fire in a residential occupancy. The model is divided into two phases. The first one, using a fire growth model, describes the rate of carbon monoxide (the main component of the combustion products) production and outflow from the fire compartment. Then the entire gas movement in the house is described as a flow in a network, with the nodes representing the enclosures, tied with flow pattern links. A series of time intervals is used to numerically solve differential equations for the carbon monoxide concentration at each node. Then it is transformed to form the stress levels as a function of time at each room.
