Coherent Lagrangian (material) structures are ubiquitous in unsteady fluid flows, often
observable indirectly from tracer patterns they create, for example, in the atmosphere and …

Flying and swimming in nature present sophisticated and exciting ventures in biomimetics,
which seeks sustainable solutions and solves practical problems by emulating nature's time …

Ensuring optimal conditions for fish, especially in terms of uniform velocity fields, is crucial
for aquaculture systems to attain self-cleaning efficiency in rearing tanks and better fish …

Transport barriers are observed inhibitors of the spread of substances in flows. The
collection of such barriers offers a powerful geometric template that frames the main …

The aquaculture industry is increasingly interested in using larger rearing tanks of near 1000
m 3 to achieve production and economic benefits. Higher Reynolds number due to that …

We present a new numerical model to simulate settling trajectories of discretized individual
or a mixture of particles of different geometrical shapes in a quiescent fluid and their flow …

Swimming organisms can escape their predators by creating and harnessing unsteady flow
fields through their body motions. Stochastic optimization and flow simulations have …

Coherent structures are persistent localized features in time-varying fields. Some examples
of physical fields in which coherence is of interest include pressure, temperature, and …

We present a combined experimental and numerical study of an idealized model of the
propulsive stroke of the turning manoeuvre in fish. Specifically, we use the framework of …

The Lagrangian eddies in the western Pacific Ocean are identified and analysed based on
Maps of Sea Level Anomaly (MSLA) data from 1998 to 2018. By calculating the Lagrangian …
