One-Dimensional Mathematical Models to Simulate Coniferous Tree Ignition

Source Title: Forest Fire Danger Prediction Using Deterministic-Probabilistic Approach

DOI: 10.4018/978-1-7998-7250-4.ch001

Abstract

The results of numerical simulation of heating a coniferous tree (pine) by cloud-to-ground lightning discharge are presented. The problem is solved in a one-dimensional formulation in a cylindrical coordinate system. A four-layer structure of the coniferous trunk is considered taking into account the core, subcortical layer, bark, and surface water layer. A parametric study of the effect of current-voltage characteristics typical of negative and positive cloud-to-ground lightning discharges on the process of heating the trunk wood has been carried out. The conditions for the ignition of a tree trunk in a typical range of variation of the parameters of the impact of the discharge are established.
