The evolution of a fire front for linear and point ignited fires is analysed and it is shown that, even in nominally uniform and permanent conditions, the rate of spread of the head fire does not remain constant in the general case of slope- and wind-driven fires due to joint convection and radiation effects. The basic case of a linear fire front without slope and without wind is one of the few cases for which the rate of spread is well defined and remains constant. if there is slope or wind in point ignition fires, the rate of spread of the head fire tends to increase while for linear ignition fires the contrary happens. It is shown that convective effects induced by the fire for steep slope terrain can produce the so-called \u2018blow-up\u2019 effect even in the absence of any other special atmospheric conditions. Therefore the definition of rate of spread of a fire and its evaluation from laboratory and field experiments is strongly questioned.<\/jats:p>","DOI":"10.1071\/wf03008","type":"journal-article","created":{"date-parts":[[2004,4,8]],"date-time":"2004-04-08T02:35:51Z","timestamp":1081391751000},"page":"101-117","source":"Crossref","is-referenced-by-count":65,"title":["On the existence of a steady state regime for slope and wind driven fires"],"prefix":"10.1071","volume":"13","author":[{"given":"Domingos X.","family":"Viegas","sequence":"first","affiliation":[{"name":"ACentro de Estudos sobre Inc\u00eandios Florestais\u2013Associa\u00e7\u00e3o para o Desenvolvimento da Aerodin\u00e2mica Industrial, Universidade de Coimbra, Apartado 10131, 3031-601 Coimbra, Portugal.
