A Bayesian methodology is used to estimate the effect of longitudinal forced ventilation on heat release rate (HRR) for fires in tunnels. The behaviour of three different sizes of pool fires with a range of forced ventilation velocities is investigated. Results are presented and the implications are discussed. It has been found that for some fires the ventilation would be expected to reduce the HRR and for some fires to increase it. Overall, expert opinions have been found to differ significantly.
