Particles moving in spatially bounded, viscous fluids Original Research Article

Using finite difference methods, we study the dynamics of a single spherical object in a two-dimensional box filled with viscous fluid under the influence of gravity. The algorithm is validated using experimental and analytic results. Special emphasis is made on the implementation and performance of two different algorithms on the parallel computer Cray-T3D. Parallel versions of the codes were tested for their speedups and the numbers are analyzed and explained to discuss further improvements.
