Fluid dynamics of smoke from enclosure fires

Laburpena

This thesis reviews the current models available to represent smoke produced by fire in enclosures, from the basic plume entrainment correlations to the most advanced CFD models. In order to review such models, several large-scale tests, with different fire sizes, fuels, physical dimensions and ambient conditions were performed in two different large-scale facilities: the Murcia Fire Atrium in Murcia, Spain, and the ITB chamber in Warsaw, Poland. The data obtained from those tests were used to understand different aspects of the current methods of numerically modelling the smoke. This thesis has highlighted the importance of properly defining the properties when numerically modelling the fire, since small differences in the input data, can generate a major impact on the output
