Flexible-walled physical model of the human left ventricle illuminated using a green laser sheet for visualization of fluid flow.
Dye injected along sandy surface is pulled sideways by pulsing jellyfish and moved vertically into the water column. Oral arms of the medusa aid in breakup of coherent large-scale vortices.
A robotic platform of 'clap and fling' interaction is used to provide kinematics corresponding to flapping flight in tiny insects with bristled wings. Vortex formation at the leading edge due to the fling interaction of wings is seen.
Streamlines showing how feeding currents of upside-down jellyfish interact with low-speed background flow moving left to right. Starting vortices from multiple cycles are observed.
Feeding in Sabellidae (tube worms) is accomplished using branched feather-duster like appendages.
Green color dye is buried well underneath the sand below an upside-down jellyfish medusa to study porewater pumping. The dye is seen emerging through the sandy substrate due to bell pulsations.
