(2009)Fire protection and life safety in buildings and transportation systems, Advanced research workshop proceedings.p.233-242 Mark abstract Prior to any CFD (‘Computational Fluid Dynamics’) calculation of a fire in a car park, a realistic fire scenario must be provided as input data. With this scenario, CFD results allow the evaluation of several characteristics of the performance of a smoke and heat control system, including:- effective limitation of the propagation of smoke (and heat) in the car park;- effective creation of a smoke-free access route from the public road on the fire storey for fire fighters to approach the fire source, i.e. facilitation of active fire suppression.- the pressure difference created by the smoke control system in the car park, which should not exceed 60Pa for the sake of opening doors.This paper presents CFD calculation for some possible fire scenarios. We do not consider the possible phenomenon of fire spread in the car park. Rather, we impose a localized fire, modeled as a heat source.
