As a highly hazardous natural disaster, the occurrence and spread of forest fires are usually affected by a variety of complex factors such as climate, terrain, vegetation, combustible materials, etc., which makes it difficult to accurately simulate the spread and extinguishing process of forest fires. The spread of forest fires and the process of water mist fire extinguishing are physically modele. The spread model adopts a tree module structure to simulate the pyrolysis reaction of tree burning, and considers the effects of temperature, wind field,mass loss rate and other factors on the spread of tree burning.In the fire extinguishing simulation experiment using water mist, the focus is on the water film formed by the water mist penetrating the flame area and the fire extinguishing effect caused by the evaporation of water, so as to prevent the spread of forest fires, successfully realizing the simulation platform for interactive fire extinguishing, which allows users to experience the process of spreading forest fires in an immersive way, and conducting water mist fire extinguishing simulation experiments with water guns, fire trunks and drones. The results of this research are of great significance for applications in the field of fire simulation.
