Reynolds number limits for jet propulsion: A numerical study of simplified jellyfish
Gregory Herschlag, Laura A. Miller
The Scallop Theorem states that reciprocal methods of locomotion, such as jet propulsion or paddling, will not work in Stokes flow (Reynolds number = 0). In nature the effective li…

Feeding Currents Generated by Upside Down Jellyfish
Terry Rodriguez, Christina Hamlet, Megan Gyoerkoe +1
We present fluid dynamics videos of the pulsing dynamics and the resulting fluid flow generated by the upside down jellyfish, Cassiopea spp. Medusae of this genus are unusual in th…

A numerical study of the effects of bell pulsation dynamics and oral arms on the exchange currents generated by the upside-down jellyfish Cassiopea spp
Christina Hamlet, Arvind Santhanakrishnan, Laura A. Miller
Mathematical and experimental studies of the flows generated by jellyfish have focused primarily on mechanisms of swimming. More recent work has also considered the fluid dynamics…
