✦ Synopsis

The burning history of a wood crib ignited at the center of its base has been investigated theoretically and experimentally. A simple energy-balance model has proven successful in predicting the radial fire-spread rates and mass burning rates for varying crib geometries with accuracies of -+ IS. Exceptions to the validity of the model were only noted for very densely packed cribs for which significant lateral spread occurred simultaneously with vertical fire spread. Cribs consisting of sticks with thicknesses of 0.635 cm, 1.905 cm and 3.17 cm were burned in the present experiments. Analysis of pressure modeling experiments has also shown that pressure modeling cannot, in general, model the fire growth rates in wood cribs.
