Abstract This report describes a study of the mechanism of the trench effect, identified as being responsible for the rapid fire growth which occurred during an escalator fire at London's King's Cross Underground Station in 1987. Experiments were carried out to examine the influence of relevant factors on flame behaviour and to provide data for the validation of computational flow dynamics (CFD) simulations. Both experiments and CFD simulations showed that the buoyant flow movement in the inclined trench depended on the trench inclination and that there was a critical angle of inclination for the trench effect to occur.
