A temporal linear stability analysis of laminar flow in weakly eccentric annular channels has
been performed. It has been shown that, even for eccentricities ε and Reynolds numbers that …

Annular Couette flow is the flow between two coaxial cylinders driven by the axial translation
of the inner cylinder. It is investigated using direct numerical simulation in long domains, with …

We carry out linear and nonlinear analyses on a flow between two infinitely long concentric
cylinders with the radii a and b subject to a sliding motion of the inner cylinder in the axial …

The linear stability of flow along an annular pipe formed by two coaxial circular cylinders is
considered. We find that the flow is unstable above a critical Reynolds number for all 0< η≤ …

The flow in an annulus driven by the axial movement of one of the cylinders has been
studied. The stationary cylinder has been fitted with axisymmetric ribs resulting in the …

The potential for mixing enhancement associated with the use of axisymmetric ribs in
annular flows has been analyzed. The enhancement relies on the use of streamwise …

The linear stability of “sliding Couette flow” of a Newtonian fluid through the annular gap
formed by two concentric cylinders having a ratio of inner to outer cylinder radii, β, and …

The problem of an incompressible flow between two coaxial cylinders with radii and
subjected to a sliding motion of the inner cylinder in the axial direction is considered. The …

We present a linear stability analysis of viscous, pressure-driven flow in an annular pipe with
a moving core. The core moves with constant speed along its axis and rotates with constant …

An investigation is conducted into the nature of the pressure-driven axial flow between
cylinders with the inner cylinder moving in the axial direction. Such a flow is often referred to …
