Direct Numerical Simulations of Three-Layer Viscosity-Stratified Flow

VOLUME 84, OCTOBER 2006 INTRODUCTION This work is motivated by a problem encountered in certain mixing processes that employ a centre line injector upstream of a static mixer. Static or motionless mixers have been adopted for a large number of blending and dispersion operations because they offer attractive features such as closed-loop operation, and no moving parts, in contrast to continuously...

Three-dimensional instability of a two-layer Dean flow

Stability of a two-layer Dean flow in a cylindrical annulus with respect to three-dimensional perturbations is studied by a global Galerkin method. It is shown that for large inner radius of the annulus ~i! the instability becomes three-dimensional if one of the fluid layers is thin, ~ii! its onset is not affected by possible small deformations of the interface, and ~iii! multiple three-dimensi...

Viscous Potential Flow Analysis of Capillary Instability

Capillary instability of a viscous fluid cylinder of diameter D surrounded by another fluid is determined by a Reynolds number J = V D `= `, a viscosity ratio m = a= ` and a density ratio ` = a= `. Here V = = ` is the capillary collapse velocity based on the more viscous liquid which may be inside or outside the fluid cylinder. Results of linearized analysis based on potential flow of a viscous...

Radiation Instability in a Stratified Shear Flow

The paper deals with a new mechanism of instability in stratified fluid caused by internal wave radiation from a shear layer. This radiation instability may be explained in terms of the negativeenergy wave concept. These waves are able to grow due to radiation losses. The dispersion relation and non-linear stage of the process are analyzed through a model with tangential velocity discontinuity....

Layer Formation in Stratified Taylor–Couette Flow

A new set of high Reynolds number experiments (Re = riΩi∆r ν ∼ 10 − 10) are conducted to examine the layer formation observed in stratified Taylor–Couette flow. A wider range of radius ratios η = ri ro (where ri and ro are the radii of the inner and outer cylinder, respectively) than previously possible is explored to examine the universality of the dependence of layer height l on U N , where U...
