Severe wildland fires are modeled based on the fundamental theories of combustion and fluid mechanics. The k-z model of turbulence is employed. A model of severe wildland fuels is given by a trade-off between computational demands and a simple but realistic model. The field is divided into inner region around the burning ring and outer region. And then the problem is analysed by using the method of matched asymptotic expansions. The outer problem is reduced to a direct problem, and the inner problem is reduced to a quasi-2D problem of flow, heat transfer and combustion .
