Abstract:
Black PMMA was burned in the cone calorimeter in two
orientations (horizontal and vertical), at imposed
radiant heat fluxes of (0, 5, 10, 25, 50, and 75) kW/m2,
and the visual appearance, flame size, heat release
rate, and mass loss rate were recorded. Various other
experimental parameters were varied. The topography of
the burned samples was also recorded, and the heat flux
to the sample was inferred from the variation of the
mass loss over the surface of the sample. The burning
was subsequently modeled using a computational fluid
dynamics (CFD) model, and various experimental,
numerical, and physical parameters were varied in the
simulations. The results provide an indication of the
ability of the fire model to predict the burning of a
simple solid sample, and also provide guidance
concerning the importance of various experimental and
numerical parameters for accurate simulation.
