Bioinspired Mechanisms and Actuation of Soft Robotic Crawlers. [PDF]

Adv Sci (Weinh)
Researchers have been developing soft materials and robotic crawlers inspired by soft‐bodied animals to mimic effective crawling in complex environments. This review explores the state‐of‐the‐art in soft crawlers, highlighting the interaction between materials, crawling mechanisms, actuation, and applications. The review concludes by providing insights

Tsunami generation by paddle motion and its interaction with a beach: Lagrangian modelling and experiment [PDF]

, 2013
A 2D Lagrangian numerical wave model is presented and validated against a set of physical wave-flume experiments on interaction of tsunami waves with a sloping beach. An iterative methodology is proposed and applied for experimental generation of tsunami-

Inertial waves in a differentially rotating spherical shell

, 2012
We investigate the properties of small-amplitude inertial waves propagating in a differentially rotating incompressible fluid contained in a spherical shell. For cylindrical and shellular rotation profiles and in the inviscid limit, inertial waves obey a

Absolute and convective instabilities in an inviscid compressible mixing layer [PDF]

, 2007
We consider the stability of a compressible shear flow separating two streams of different speeds and temperatures. The velocity and temperature profiles in this mixing layer are hyperbolic tangents.

Internal Capillary-Gravity Wilton Ripples

Water Waves
Periodic traveling waves at the interface of two incompressible, inviscid fluids subject to gravity and surface tension are studied. We focus on the case in which the linearization about the quiescent state has a two-dimensional kernel.

Inviscid Criterion for Decomposing Scales

, 2018
The proper scale decomposition in flows with significant density variations is not as straightforward as in incompressible flows, with many possible ways to define a `length-scale.' A choice can be made according to the so-called \emph{inviscid criterion}

A note on the breathing mode of an elastic sphere in Newtonian and complex fluids

, 2015
Experiments on the acoustic vibrations of elastic nanostructures in fluid media have been used to study the mechanical properties of materials, as well as for mechanical and biological sensing.

Compressibility effects on the Rayleigh-Taylor instability growth between immiscible fluids

, 2003
The linearized Navier-Stokes equations for a system of superposed immiscible compressible ideal fluids are analyzed. The results of the analysis reconcile the stabilizing and destabilizing effects of compressibility reported in the literature.

Singular diffusionless limits of double-diffusive instabilities in magnetohydrodynamics [PDF]

, 2017
We study local instabilities of a differentially rotating viscous flow of electrically conducting incompressible fluid subject to an external azimuthal magnetic field. In the presence of the magnetic field the hydrodynamically stable flow can demonstrate
