Определение теплофизических свойств лесных горючих материалов при оценке скорости распространения импульса тепла в толще образца

Abstract

Experimental studies to determine the thermophysical properties (thermal conductivity, specific heat) of forest combustible materials were made. Typical materials of the softwood and deciduous forests of Tomsk region geographic latitudes were used as samples. Scales of temperature influence on thermophysical properties of a forest cover were determined. The comparative analysis of the received values of thermophysical characteristics for pine needles of and birch leaves of the boreal massif with earlier published results was carried out. The received results will be able to form a basis for establishment of features and regularities of influence of coefficient of thermal conductivity, specific heat of on process of the suppression of forest combustible materials thermal decomposition reaction at local ignition of a forest zone.
