Engineering Physics Annotation << Back Mathematical simulation of deciduous tree ignition by ground lightning discharge taking into account reactive wood localisation N.V. Baranovskiy, G.V. Kuznecov Physical and mathematical statement and results of the numerical simulation of a problem about deciduous tree (birch) ignition by ground lightning discharge are presented. The problem is considered in flat statement in cylindrical system of coordinates. Heat transfer features taking into account localization of reactive wood are considered. The parametrical analysis is carried out and conditions of tree trunk ignition in a typical range of parameters of influence of negative and positive discharges are obtained. Keywords: ignition, ground lightning discharge, deciduous tree, reactive wood. E-mail: firedanger@narod.ru
