Drill String Drag and Torque Test Device Design
Shiyou jixie, 2019 The existing drag and torque theoretical model has many assumptions, leading to a large difference between the calculated value and the true value, which seriously restricts the study of the mechanical behavior of the drill string and the optimization of

Force and torque acting on particles in a transitionally rough open channel flow
, 2011 Direct numerical simulation of open channel flow over a geometrically rough wall has been performed at a bulk Reynolds number of approximately 2900. The wall consisted of a layer of spheres in a square arrangement. Two cases have been considered.

Dust Settling and Rapid Planetary Migration
, 2010 Planetary migration is essential to explain the observed mass-period relation for exoplanets. Without some stopping mechanism, the tidal, resonant interaction between planets and their gaseous disc generally causes the planets to migrate inward so ...
