Tiny reversible rearrangement transitions in granular systems
(2006)
Very dense bidimensional systems of inelastic hard disks excited from the base are studied by means of Newtonian event driven molecular dynamics. A stationary regime is reached where almost perfect crystallographic order ...
Aplicación de la técnica tds a un yacimiento compuesto con fluidos dilatantes no newtoniano/newtoniano
(Universidad Nacional de Colombia - Facultad de Ingeniería, 2011)
Por muchos años, los fluidos no Newtonianos, tales como los polímeros, se han usado en la industria del petróleo como agentes de fracturamiento y en lodos de perforación. Estas soluciones las cuales normalmente contienen ...
Asymptotic regimes of ridge and rift formation in a thin viscous sheet model
(American Institute of Physics, 2008-04)
We numerically and theoretically investigate the evolution of the ridges and rifts produced by the convergent and divergent motions of two substrates over which an initially uniform layer of a Newtonian liquid rests. We ...
Numerical Simulations of the Flow Around a Spinning Projectile in Subsonic Regime
(Planta Piloto de Ingeniería Química, 2008-12)
The unsteady flow around a 155 mm projectile governed by the Navier-Stokes (NS) equations is numerically solved with a Large Eddy Simulation (LES) scheme, together with the SubGrid Scale (SGS) solved by a Smagorinsky model ...
Physical approximations for the nonlinear evolution of perturbations in inhomogeneous dark energy scenarios
(AMER PHYSICAL SOC, 2009)
The abundance and distribution of collapsed objects such as galaxy clusters will become an important tool to investigate the nature of dark energy and dark matter. Number counts of very massive objects are sensitive not ...
Self-similar asymptotics in non-symmetrical convergent viscous gravity currents
(Institute of Physics Publishing, 2009-12)
We investigate the evolution of the ridge produced by the non-symmetrical convergent motion of two substrates over which an initially uniform layer of a Newtonian liquid rests. The lack of symmetry of the flow arises because ...
