A new algorithm, which is exceptionally fast for certain choices of numerical parameters, is described for the study of nonlinear, incompressible flow between two rotating disks. Typical examples for Reynolds number R in ...

A new numerical method is developed for the solution of steady state, viscous, incompressible flow between two rotating spheres. The Navier-Stokes equations are approximated by a triple sequence of linear problems, each ...

Newtonian gravitation is studied from a discrete point of view in that the dynamical equation is an energy conserving difference equation. Application is made to planetary type, nondegenerate three-body problems and several ...

Stability limitations, inherent in a previously developed discrete approach to mechanics, are relaxed by introducing two alternative approaches, one explicit and the other implicit. Computer results for motion in a nonlinear ...
