Cavity Flow of a Particle Fluid

Donald Greenspan

A new, arithmetic, computer oriented approach to fluid modeling is developed and implemented. Fluids are simulated by finite particle sets which are subjected both to gravity and to molecular type force interactions. A particle liquid is generated on the UNIVAC 1110 and the classical cavity flow problem is studied. The method is economical and applies easilty with relatively few particles to phenomena with significant, gross motions.
