An application method of free burn heat release rate (HRR) data for a single seater sofa to predict the burning behavior in a compartment is proposed. A single seater sofa was burnt in an open environment to measure the HRR using a furniture calorimeter. The time-HRR curve was fitted with a model of burning of a cubic polyurethane block developed earlier. The model included the flame spread over horizontal, downward and lateral directions. The flame spread rates were increased if the block received radiative heat from external heat sources other than from the flame. The thermal radiation feedback from the flame, smoke layer, and heated wall surfaces was coupled with the burning model. Using the coupled model, the burning and spread rate of several sofas and a table in a small compartment was calculated and compared with experimental results. The model could reproduce the trend for the increase in HRR qualitatively. However, the time to spread to an adjacent object was not in good agreement. If the time to spread was given input to the model, other parameters such as compartment temperature and so on could be calculated with reasonable agreement.

Facade fires being a disastrous hazard for high rise building, as several historical and recent incidents have shown, have attracted the interests of numerous fire scientists, engineers and regulators. This work has as an objective to present issues in this area that are challenging and need further attention. It focuses on characterizing the flame height and heat fluxes from facade flames produced from under-ventilated enclosure fires on a facade that is not flammable. Such an investigation is an important consideration for practical applications as well as a prerequisite for examining fire spread on flammable facades and for designing a test for modern facade assemblies. The mass pyrolysis rates and burning of real fuels are discussed in under ventilated enclosures, rectangular or corridor like, for various openings presenting the current state and some critical issues. Facade flames are analyzed from experiments using gaseous burners to have control on the fuel supply rate by introducing physical length scales for the opening geometries to model flame heights and heat fluxes. An important parameter for the facade flames is the excess heat release rate of the fuel burning outside the enclosure. Finally, applications for facade flames with sidewalls and facade flames from two openings are presented.
