abstract = {The instability of a liquid layer coating the surface of a thin cylindrical
wire is studied experimentally and numerically with negligible gravity
effects. The initial uniform film is obtained as the residual of
a sliding drop, and the thickness measurements are performed with
an anamorphic optical system that compresses the vertical scale (allowing
to observe several wavelengths) and widens the horizontal one (to
follow in detail the evolution of local minima and maxima). Experimental
timelines showing the growth and position of the maxima and minima
are compared with linear theory and fully nonlinear simulations.
A primary mode grows in the early stages of the instability, and
its wavelength $\lambda$1 is not always in agreement with that corresponding
to the maximum growth rate predicted by the linear theory $\lambda$m.
In later stages, a secondary mode appears, whose wavelength is half
that of the primary mode. The behaviour of the secondary mode allows
us to classify the experimental results into two cases, depending
on whether it is linearly stable (case I) or unstable (case II).
In case I, the amplitude of the secondary mode remains small compared
with that of the primary one, while in case II both amplitudes may
become very similar at the end. Thus, the distance between the final
drops may be quite different from that seen between initial protuberances.
The analysis of the experiments allows us to define a simple criterion
based on the comparison between $\lambda$1 and $\lambda$m. Contrary
to the predictions of widely used previous quasi-static theories,
experiments show that the relation between maximum and minimum of
the primary mode is better approximated by a kinematic model based
on the assumption that primary maxima increase as fast as the minima
decrease. Numerical simulations confirm this hypothesis.},

isolating the effect of van der Waals interactions for nanoscale
rivulets, and of gravity for macrosize rivulets, we are able to analyze
the influence of these forces on the stability. We discuss in detail
the scaling of the emerging wavelengths (distance between drops formed
after the breakup process) with the rivulet cross-sectional area.
Perhaps surprisingly, we uncover close connection between this scaling
and the one for the breakup of a free-space fluid jet (Rayleigh–Plateau

find that the finite size effects are considerably different from

by constant fluid flux, in the present problem the base flow is time
dependent. We present a method to carry out consistently linear stability
analysis, based on simultaneously solving the time evolution of the
base flow and of the perturbations. The analysis is performed numerically
by using a finite-difference method supplemented with an integral
method developed here. The computations show that, after a short
transient stage, imposed perturbations travel with the same velocity
as the leading contact line. The spectral analysis of the modes evolution
shows that their growth rates are, in general, time dependent. The
wavelength of maximum amplitude, $\lambda$max, decreases with time
until it reaches an asymptotic value which is in good agreement with
experimental results. We also explore the dependence of $\lambda$max
on the cross sectional fluid area A, and on the inclination angle
$\alpha$ of the substrate. For considered small A’s, corresponding
to small Bond numbers, we find that the dependence of $\lambda$max
on A is in good agreement with experimental data. This dependence
differs significantly from the one observed for the films characterized
by much larger A’s and Bond numbers. We also predict the dependence
of $\lambda$max on the inclination angle $\alpha$.},

the initial condition is generated from a horizontal fluid filament
(PDMS) of typical diameter ≈ 0.4 mm, and the flow is probed with
two optical techniques: one based on an anamorphic system, and the
other on the schlieren method. The first one yields the thickness
profile and the second one captures the bidimensional pattern of
the transversal film instability. The numerical simulations are performed
under the lubrication approximation and using a precursor film to
overcome the contact line divergence. The comparison between numerical
and experimental profiles shows a very good agreement, and therefore
allows to estimate the thickness of the precursor film needed to
model the flow. We find that this thin precursor (of thickness 43
nm) is very demanding for the numerical description of the instability,
since it requires the use of a very fine grid. We show that the use
of thicker precursor allows to obtain numerical results which describe
qualitatively well the experimental data. In order to study the early
times of the instability, we develop a linear model to account for
the evolution of the modal amplitudes of the spatial Fourier spectrum
of the contact line of the advancing front (frontline). The model
is in good agreement with both experiments and simulations for the
appropriate precursor film thickness in each case. We find that the
precursor film thickness mainly influences the growth rates of the
unstable modes, but it does not modify the main features of instability
development.},

year = {2002},
volume = {32},
pages = {945},
number = {4},
abstract = {The compressible magnetohydrodynamic Kelvin-Helmholtz instability
occurs in two varieties, one that can be called incompressible as
it exists in the limit of vanishing compressibility (primary instability),
while the other exists only when compressibility is included in the
model (secondary instability). In previous work we developed techniques
to investigate the stability of a surface of discontinuity between
two different uniform ows. Our treatment includes arbitrary jumps
of the velocity and magnetic fields as well as of density and temperature,
with no restriction on the wave vector of the modes. Then it allows
stability analyses of complex configurations not previously studied
in detail. Here we apply our methods to investigate the stability
of various typical situations occurring at different regions of the
front side, and the near anks of the magnetopause. The physical conditions
of the vector and scalar fields that characterize the equilibrium
interface at the positions considered are obtained both from experimental
data and from results of simulation codes of the magnetosheath available
in the literature. We give particular attention to the compressible
modes in configurations in which the incompressible modes are stabilized
by the magnetic shear. For configurations of the front of the magnetopause,
which have small relative velocities, we find that the incompressible
MHD model gives reliable estimates of their stability, and compressibility
effects do not introduce significant changes. However, at the anks
of the magnetopause the occurrence of the secondary instability and
the shift of the boundary of the primary instability play an important
role. Consequently, configurations that are stable if compressibility
is neglected turn out to be unstable when it is considered and the
stability properties are quite sensitive on the values of the parameters.
Then compressibility should be taken into account when assessing
the stability properties of these configurations, since the estimates
based on incompressible MHD may be misleading. A careful analysis
is required in each case, since no simple rule of thumb can be given.},

with the case without magnetic field shear. Second, new unstable
modes appear (called secondary) which owe their existence to compressive
perturbations. The secondary modes (of compressive character) determine
the stability for values of velocity of the unperturbed flow that
correspond to stable primary modes. In these cases the compressive
modes do not disappear and may have appreciable growth rates. Therefore,
compressibility effects may be relevant when discussing the stability
of problems with magnetic field shear. Diagrams of stability and

jump, and for any relative orientation of B, u and k (B is continuous).
Stability is analysed by means of a general procedure that allows
discussion of any configuration and all kinds of perturbations. The
boundaries between modes of different kinds are discussed. In contrast
to the case of uniform density, for a density jump there are no monotonically
unstable modes, only overstabilities. The unstable modes belong to
two types. Those with the largest growth rates tend to monotonically
unstable modes in the limit of uniform density, and are related to
the torsional Alfv\'{e}n mode. The other overstable modes have no
analogue among the purely incompressible modes, and occur in a range
of U that is stable in the incompressible limit. We derive bounds
for the growth rate of the instability. The present results may serve
