Is the Zero Reynolds Number Approximation Valid for Ciliary Flows?
Physical Review Letters, 2019 Stokes equations are commonly used to model the hydrodynamic flow around cilia on the micron scale. The validity of the zero Reynolds number approximation is investigated experimentally with a flow velocimetry approach based on optical tweezers, which allows the measurement of periodic flows with high spatial and temporal resolution.

Measurement of ciliary beating and fluid flow in the zebrafish adult telencephalon
STAR Protocols, 2022 Summary: Motile cilia are hair-like structures that move and propel fluid, playing important roles in the physiology of organs. Here, we present a protocol to visualize and measure ciliary beating and cerebrospinal fluid (CSF) flow in the telencephalon ...

Mucous Flow and Ciliary Activity in the Trachea of Rats Exposed to Pulmonary Irritant Gas [PDF]
Occupational and Environmental Medicine, 1956 In the field of occupational hygiene questions frequently arise concerning the effect on the respira tory tract of inhaled gases and of vapours from industrial solvents. The action of such agents is primarily on the mucosa of the respiratory tract. Any study of this question necessarily involves determination of the rates of mucous flow and ciliary ...
