| dc.description | In selective withdrawal, fluid is withdrawn through a nozzle suspended above the flat interface separating two immiscible, density-separated fluids of viscosities $ν_{upper}$ and $ν_{lower} = λν_{upper}$. At low withdrawal rates, the interface gently deforms into a hump. At a transition withdrawal rate, a spout of the lower fluid becomes entrained with the flow of the upper one into the nozzle. When $λ= 0.005$, the spouts at the transition are very thin with features that are over an order of magnitude smaller than any observed in the humps. When $λ= 20$, there is an intricate pattern of hysteresis and a spout appears which is qualitatively different from those seen at lower $λ$. No corresponding qualitative difference is seen in the hump shapes. | |
