Threshold phenomena in erosion driven by subsurface flow
[1] We study channelization and slope destabilization driven by subsurface (groundwater) flow in a laboratory experiment. The pressure of the water entering the sand pile from below as well as the slope of the sand pile are varied. We present quantitative understanding of the three modes of sediment mobilization in this experiment: surface erosion, fluidization, and slumping. The onset of erosi...
متن کامل1 Abrupt contraction flow of magnetorheological fluids
Contraction and expansion flows of magnetorheological fluids occur in a variety of smart devices. It is important therefore to learn how these flows can be controlled by means of applied magnetic fields. This paper presents a first investigation into the axisymmetric flow of a magnetorheological fluid through an orifice (so-called abrupt contraction flow). The effect of an external magnetic fie...
متن کاملCritical phenomena in perfect fluids
We investigate the gravitational collapse of a spherically symmetric, perfect fluid with equation of state P = (Γ − 1)ρ. We restrict attention to the ultrarelativistic (“kinetic-energy-dominated”, “scale-free”) limit where black hole formation is anticipated to turn on at infinitesimal black hole mass (Type II behavior). Critical solutions (those which sit at the threshold of black hole formati...

Macro-micro Interlocked Simulation for Multiscale Phenomena
A new methodology for the simulation of multiscale processes, called Macro-Micro Interlocked (MMI) Simulation, is introduced. The MMI simulation is carried out by the two-way connection of different numerical models, which may handle macroscopic and microscopic dynamics, respectively. The MMI simulation are applied to several multiscale phenomena, for instance, cloud formation, gas detonation, ...
