Computer Studies of Swirling Particle Fluids and the Evolution of Planetary-Type Bodies

Donald Greenspan, John Collier

In this paper a particle-type model is applied to the study of evolving swirling fluids. Of basic importance is a natural, self-reorganizing property of the system. High-speed digital computation is essential for the resolution of associated initial-value problems. Examples are described which incorporate local, molecular-type forces and long-range, gravitational forces. Moon-like and planetary-like bodies thus evolve in a natural way. Extensive computer examples are given.
