A study is undertaken of both parallel flow and cross-flow in the viscous sublayer generated
by a fluid streaming along a grooved surface, with the aim of clarifying the phenomena that …

This review highlights the profound and unexpected ways in which viscosity varying in
space and time can affect flow. The most striking manifestations are through alterations of …

The Oldroyd-B model has been used extensively to predict a host of instabilities in shearing
flows of viscoelastic fluids, often realized experimentally using polymer solutions. The …

Two-fluid dynamics is a challenging subject rich in physics and prac tical applications. Many
of the most interesting problems are tied to the loss of stability which is realized in …

The formation of bubbles by flow focusing of a gas and a liquid in a rectangular channel is
shown to depend strongly on the channel aspect ratio. Bubble breakup consists in a slow …

There is extensive literature on the stability of parallel two-phase flow, both in the context of
liquid-liquid as well as gas-liquid flow. Aimed at making this literature more transparent, this …

Results are given for experiments on water-lubricated pipelining of 6.01 P cylinder oil in a
vertical apparatus in up-and downflow in regimes of modest flow rates, less than 3 ft/s …

AN impressive amount of evidence supports the proposal of Alvarez et al. 1, 2 that the
Cretaceous era was ended abruptly by the impact of a comet or asteroid. The recent …
