Response of free-burning fires to nonsteady wind

A speculative, phenomenological model is formulated for the time-varying intensity and spread rate of a free-burning fire under the influence of nonsteady wind. The model is linearized by approximations and explicit solutions derived for the amplitude response of spread rate and…

The chemistry of flames

'...With the aid of modern laboratory techniques it is possible to detect not only the end products of combustion proccsses but also many substances that appear transiently in the course of burning. As a result fire has come to be understood chemically as an intricate network of…

The variability of wind-aided free-burning fires

An empirical representation of the power spectral density of horizontal gustiness near the ground in high winds is combined with a theoretical model for the response of free-burning fires to nonsteady wind to predict the variability of spread rate and intensity of wind-aided…

An evaluation of the carbon balance technique for estimating emission factors and fuel consumption in forest fires

Eighteen experimental fires were used to compare measured and calculated values for emission factors and fuel consumption to evaluate the carbon balance technique. The technique is based on a model for the emission factor of carbon dioxide, corrected for the production of other…
