The Motion of a Rigid Particle of Arbitrary Shape in an Unbounded Fluid, symmetry requires that the hydrodynamic force on the particle be parallel to its direction of motion. Before proceeding to other cases, where it is impossible to take advantage of such symmetry, it is appropriate to investigate the effect of particle orientation on resistance in a general way.

Interaction between Two, or More Particles,nal forces, typically gravity. The particles are supposed sufficiently close to interact hydrodynamically. It is assumed that the particles are sufficiently distant from boundary walls for the surrounding fluid to be regarded as unbounded. Attention will be predominantly directed to situations whereDAFT 发表于 2025-3-27 11:01:12

John Happel,Howard Brennerraphy have taken shape from the Late Paleozoic to modern times. A uniform basement of the basin was amalgamated from terranes of different origin as late as in the Middle Miocene. Accordingly, older landforms had been created on either the European or the African plate, while since the Miocene geomo
