Mathematical simulation of heat transfer at coniferous tree ignition by cloud-to-ground lightning discharge
National Research Tomsk Polytechnic University, Institute of Power Engineering, 634050 Tomsk, Russia
Published online: 27 August 2014
Numerical simulation results of coniferous tree heating by cloud-to-ground lightning discharge are presented. Pine tree is under consideration. The problem is solved in one-dimensional statement in cylindrical system of coordinates. Parametric investigation of volt-ampere characteristics influence on stem heating process was lead for negative and positive ground lightning discharges. Conditions of coniferous tree ignition in a typical range of influence parameters change are established.
