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.
Researchers from University of Tsukuba investigated the propulsion mechanism by visualizing water flow around a swimmer during underwater dolphin-kick swimming in a water channel via particle image velocimetry. Their findings ...
