Discovery of fundamental principles which govern and limit effective locomotion (self-
propulsion) is of intellectual interest and practical importance. Human technology has …

Flexible slender structures are ubiquitous in biological systems and engineering
applications. Fluid-structure interaction (FSI) plays a key role in the dynamics of such …

Here, we present ultragentle soft robotic actuators capable of gras** delicate specimens
of gelatinous marine life. Although state-of-the-art soft robotic manipulators have …

The propulsive performance and vortex dynamics of a two-dimensional model for the
jellyfish-like propulsion with burst-and-coast strategy are investigated using a penalty …

In many swimming and flying animals, propulsion emerges from the interplay of active
muscle contraction, passive body elasticity and fluid–body interaction. Changes in the active …

Fluid-structure systems occur in a range of scientific and engineering applications. The
immersed boundary (IB) method is a widely recognized and effective modeling paradigm for …

The influence of uniform background co-flow on the propulsive characteristics of starting jets
with stroke ratios (length to diameter ratio, L/D) from 1 to 5 and velocity ratios (ratio of co-flow …

We present and analyze a series of benchmark tests regarding the application of the
immersed boundary (IB) method to viscoelastic flows through and around non-trivial …
