Numerical Studies of Flow Between Rotating Coaxial Disks

A new algorithm, which is exceptionally fast for certain choicesof numerical parameters, is described for the study of nonlinear,incompressible flow between two rotating disks. Typical examplesfor Reynolds number R in the range 10 R 2000 are describedand discussed. Comparisons are made with the limited availableresults generated by other methods.     

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

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