Publicación Influence of temperature on air runoff in the propagation of a forest fire(['Universidad Nacional de Educación a Distancia (España)', 'Universidad Politécnica de Madrid. Departamento de Ingeniería Mecánica'], 2022) Gonçalves, Inês; Marquer, João; Silva, João; Teixeira, José; Alvelos, Filipe; Teixeira, SenhorinhaWildfires are a worldwide phenomenon that endangers the ecosystems and all its surroundings. Because forest fires are unpredictable phenomena, it is critical to maximize the instruments employed to mitigate their harmful effects. The main purpose of this work is the development of a model that allows to perform numerical simulations of atmospheric flows over a complex terrain through a CFD model considering the momentum and energy equations, through the use of the commercial software Ansys Fluent. It was concluded that the presence of the forest causes a modification in the velocity profile due to the drag produced by its presence, and the values could be used in a mathematical model to obtain the fire rate of spread and fire line intensity. Through the combustion simulations it was also possible to verify that high temperatures can result in convection currents with high speeds.
