Interactive Simulation of Fire

In this paper we describe a fast and interactive model to simulate and control the fire phenomenon. We use a modified interactive fluid dynamics solver to describe the motion of a 3-gas system. We simulate the motion of oxidizing air, fuel gases, and exhaust gases. The burning process is simulated by consuming fuel and air based on the amounts of fuel and air inside each grid cell. The combustion process produces heat, and we model the resulting spread of temperature through the system. The heat distribution induces convection currents in the air, causing the flame to take the appropriate shape. By modeling heat distribution, we also simulate the spread of fire to and self-ignition in other combustible solids.
