Simulations of evacuation time

CFD simulation of evacuation are conducted of three-dimensional object model. Properly defined objectives in the worst fire scenarios case associated with the most difficult conditions of evacuation.

In analyzing the movement of people in the facility included as follow:

• users number,
• age and sex,
• mobility ,
• degree of knowledge of the object,
• start of the evacuation rate,
• number of people moving at the same time,
• degree of opacity,
• temperature of hot gases and ambient air,
• concentration of toxic gases.

It is possible to perform simultaneous evacuation, fire development , spread of smoke and the evacuation process. Such a simulation allows a precise evaluation the time required to evacuate people, the protected passages and escape routes, smoke and temperature do not occur that prevent the safe evacuation, according to with the technical and construction applicable provisions.
