Abstract
This article presents a numerical study on the thermal response of a trunk tree, in a forest fire environment, provided with an incorporated water control system. This numerical control system activates the water system when the temperature rises above 60 ℃. The numerical model of the trunk tree is based on energy balance integral and differential equations. The virtual trunk tree geometry was developed used adaptive mesh generation. The numerical simulation was made for a fire front propagation at a constant fire spread rate of 0.01 m/s. The temperature distribution in the pine tree trunk, obtained for a flame temperature of 500 ℃, will make it possible to identify the areas of the trunk tree that will reach temperatures that will trigger the control system. The results show that the water system will mostly be activated when the fire is on the upstream side of the tree trunk.
