TY - JOUR PY - 2001// TI - Variation of heat release rate with forced longitudinal ventilation for vehicle fires in tunnels JO - Fire safety journal A1 - Carvel, RO A1 - Beard, Alan N.

However, the influence of such ventilation on fire development and fire spread has rarely been considered. This paper presents the results of a study using a Bayesian methodology to estimate the effect of forced longitudinal ventilation on heat release rate (HRR) for fires in tunnels. The behaviour of car and heavy goods vehicle (HGV) fires with a range of forced ventilation velocities is investigated. Results are presented and the implications are discussed. It has been found that forced ventilation has a great enhancing effect on the HRR of HGV fires, but has little effect on the HRR of car fires.
