Electrostatic forces in fibrous filters—a review

Among various devices for removing submicrometer particles from a gas stream, fibrous filters have the advantages of providing high collection efficiencies at low-pressure drop. Even in the absence of electrostatic forces, a fibrous filter captures particles efficiently by inertial impaction, interception, and convective Brownian diffusion. Application of electrostatic forces can significantly ...

Pulsed jet dynamics of squid hatchlings at intermediate Reynolds numbers.

Squid paralarvae (hatchlings) rely predominantly on a pulsed jet for locomotion, distinguishing them from the majority of aquatic locomotors at low/intermediate Reynolds numbers (Re), which employ oscillatory/undulatory modes of propulsion. Although squid paralarvae may delineate the lower size limit of biological jet propulsion, surprisingly little is known about the hydrodynamics and propulsi...

morphokinematics for undulatory swimmers at intermediate Reynolds numbers

We noted in the main text the high Strouhal number corresponding to both our and Kern & Koumoutsakos (2006) optimal e cient swimmer's, and attributed this to the lower Reynolds number used in these computational works compared with the analyses in Triantafyllou et al. (1993); Taylor et al. (2003), consistent with Gazzola et al. (2014). However, both in Kern & Koumoutsakos (2006) and in the curr...
