Biological fluid dynamics is a research area that applies the principles and methods of fluid mechanics to analyze flows generated by, within, or around living organisms across scales from subcellular to ecological. It investigates how fluid properties, boundary conditions, and flexible or actuated biological structures interact to determine transport, locomotion, feeding, signaling, and morphogenesis in systems such as blood circulation, ciliary flows, microorganism swimming, plant transpiration, and animal flight or swimming. The field integrates continuum mechanics, low- and high-Reynolds-number hydrodynamics, nonlinear dynamics, and computational modeling with experiments to elucidate biophysical mechanisms and to inform biomedical and bioinspired engineering applications.
The motion of snakes has long fascinated humans: they undulate, they sidewind, they crawl, they even fly.

Researchers at the Georgia Institute of Technology and India's National Center for Biological Sciences have found that yeast clusters, when grown beyond a certain size, spontaneously generate fluid flows powerful enough to ...
Water makes up around 60% of the human body. More than half of this water sloshes around inside the cells that make up organs and tissues. Much of the remaining water flows in the nooks and crannies between cells, much like ...

When exposed to periodic driving, which is the time-dependent manipulation of a system's parameters, quantum systems can exhibit interesting new phases of matter that are not present in time-independent (i.e., static) conditions. ...
From bird flocking to fish schooling, many biological systems exhibit some type of collective motion, often to improve performance and conserve energy. Compared to other swimmers, manta rays are particularly efficient, and ...
