| Zusammenfassung: | Title screen There are noticeable differences in the structure of deciduous and coniferous trees. This causes differences in how the process of a cloud-to-ground lightning discharge igniting various trees occurs. Various structural heterogeneities can affect integral characteristics of the process of how the tree ignites. This article numerically investigates the gas-phase ignition of coniferous tree by the cloud-to-ground lightning discharge in approaching of “ideal” crack in the bark. The crack is considered as “ideal” if it passes through the whole height of tree trunk. Carbon monoxide oxidation by oxygen to carbon dioxide serves as the basic chemical reaction. The problem is solved in the flat statement using polar coordinates. Ignition is described by the system of the non-stationary nonlinear equations of heat conductivity and diffusion with corresponding initial and boundary conditions. We conducted theparametricalresearch of how volt-ampere characteristics affect the process of tree trunk ignition. We established how the bark structural heterogeneity affects the ignition conditions. Режим доступа: по договору с организацией-держателем ресурса |
