This paper describes a method
for animating suspended particle explosions.
Rather than modeling the numerically troublesome, and largely
invisible blast wave, the method uses a relatively stable incompressible
fluid model to account for the motion of air and hot gases.
The fluid's divergence field is adjusted directly to account for
detonations and the generation and expansion of gaseous combustion
products. Particles immersed in the fluid track the motion
of particulate fuel and soot as they are advected by the fluid.
Combustion is modeled using a simple but effective process governed
by the particle and fluid systems. The method has enough flexibility
to also approximate sprays of burning liquids. This paper
includes several demonstrative examples showing air bursts, explosions
near obstacles, confined explosions, and burning sprays. Because
the method is based on components that allow large time integration
steps, it only requires a few seconds of computation per frame
for the examples shown.
