Abstract

This work aims to investigate the fire development of a liquid pool in a corridor and externally venting flames (EVF) aiming to contribute to fundamental fire research towards ensuring fire safety of high-rise buildings. This study aims at experimentally and numerically investigate, with the use of FDS, EVF development in corridor-like geometries to identify the key factors influencing their characteristics and impact on the façade. A parametric study has also been performed to investigate the effects of ventilation and fuel distribution. Numerical results of gas temperatures, flame heights and heat fluxes for the interior and exterior of the configuration were compared to experimental data. In the corridor interior, good qualitative and occasionally quantitative agreement is observed for the gas temperatures. The performance of FDS in predicting EVF gas temperatures and heat flux to the adjacent façade is improved for larger opening sizes. Regarding heat flux at the façade, good quantitative agreement is observed, especially at lower heights.
