Abstract: To address the problem of multiphysics coupling in combustion simulation, a numerical simulation method is proposed based on particles and polygonal surface meshes. The proposed method establishes a multiphysics coupling model for the combustion process by considering physical processes such as fluid flow, heat conduction, chemical reactions, turbulent disturbances, and wind-field effects, and analyzes the basic parameters and dynamic evolution characteristics of combustion. During the coupling modeling process, the complex interactions and coupling effects among flame propagation, heat transfer, airflow disturbance, and combustion reactions are specifically characterized. The proposed method can accurately simulate heat transfer, flame propagation, and their influence on the surrounding environment during combustion, thereby predicting fire-spread paths and potential hazards. Simulation results show that the proposed method can effectively predict the interactions among fluid flow, heat transfer, chemical reactions, and wind-field disturbances, as well as in capturing the dynamic characteristics of combustion.

Key words: combustion, multi-physical fields, particles, propagation, simulation
