Simulation of Fire by Fluid Equations and Heat Conduction Equation

Abstract

Display of fire using CG is used in entertainments such as movies, applications of fire simulation for the training of extinguishing fire, and disaster prevention. In this paper, we propose a technique for simulating fire spread taking into account the various properties of materials. In our method, the flame dynamics is obtained by the numerical computation of the fluid equations and the conduction of the heat in the materials are computed by the heat conduction equation. In our method, the various combustion processes are simulated by specifying ignition points and the thermal diffusivity depending on the types of materials.
