Formatted Abstract/Summary
Tall buildings are currently designed on the basis of a “worst case scenario” formulation for fires. This worst case scenario is based on extensive testing done in the 1960’s and 1970’s. These tests had to critical characteristics, they were mostly conducted in small compartments with almost cubic geometry and they were very poorly instrumented. Modern buildings have compartments that are in many cases very large with aspect ratios far from cubic. This is important in that the aspect ratio defines the nature of turbulent mixing and oxygen supply to the combustion zone. Furthermore, for small cubic compartments mixing is intense resulting in an almost homogeneous distribution of temperature and species, in a large compartment the gradients of temperature and species are very significant. Low instrumentation density can be justified for the former but not for the latter. This presentation discusses a series of large scale experiments conducted with a compartment 18 m x 5 m x 2 m where the fire was allowed to propagate. Temperatures, heat fluxes, velocities and species were measured with a resolution consistent with typical CFD fire models.
