Mathematical Simulation of Heat Transfer in Heterogenous Forest Fuel Layer Influenced by Heated Up to High Temperatures Steel Particle

Abstract

Abstract. Heterogeneity of forest fuel layer renders the important influence on forest fire occurrence processes. One of sources of the raised temperature on forested territories is metal particles heated up to high temperatures. Such particles can be formed as a result of welding of metals on forested territories. The present paper represents the heat transfer research in forest fuel at the influence of metal particle heated up to high temperatures. The heterogonous forest fuel layer with inclusions of small wooden branches and chips is considered. Such object research is urgent especially at fire forecasting on forest cutting. The technology of mathematical simulation is used. The two-dimensional problem of heat transfer in forest fuel layer structure with wood inclusions is solved.

Forest Fuel Drying, Pyrolysis and Ignition Processes during Forest Fire: A Review

“…A mathematical model of the forest fuel ignition by a heated metal particle is considered in [157]. According to the mathematical statement, a heated particle falls on the forest fuel layer with heterogeneous wood inclusions in it.…”

Spatial Mathematical Model of Heat Transfer in Human Skin Influenced by Heated up to High Temperatures Particle

“…Such systems, in turn, can find application in structures of the Ministry of Emergency Measures, medical institutions and departments of protection works or a civil defense at the industrial enterprises. It is necessary to notice, that development of the complex deterministic-probabilistic approach on the basis of methods of the forest fire danger forecast [21][22][23][24], information-computational technologies [25][26][27] taking into account the developed mathematical models of heat transfer in human skin is possible. Such system will allow to predict as forest fire danger, and as to estimate influence of fires on the persons.…”

Technologies of Physical Monitoring and Mathematical Modeling for Estimation of Ground Forest Fuel Fire Condition

“…Pre-production operation of these installations in territory of a large forest near to settlement Ulan-Ude (Buryatiya, Russia) spent. Data of supervision which can be used at operation of the determined mathematical models of drying and ignition of forest fuel layer obtained [17][18][19]. The hardware-software network of forest fire danger monitoring in controllable forest territories can be created on the basis of such installations and the software realizing of mathematical models of drying and ignition of forest fuel [20][21][22][23].…”
