I review the concept of optimal vortex formation and examine its relevance to propulsion in
biological and bio-inspired systems, ranging from the human heart to underwater vehicles …

Heart disease remains a leading cause of death worldwide. Previous research has indicated
that the dynamics of the cardiac left ventricle (LV) during diastolic filling may play a critical …

In this paper we apply dynamical systems analyses and computational tools to fluid transport
in empirically measured vortex ring flows. Measurements of quasisteadily propagating …

Compartmentalization of biomolecules within lipid membranes is a fundamental requirement
of living systems and an essential feature of many pharmaceutical therapies. However …

Flow patterns generated by medusan swimmers such as jellyfish are known to differ
according the morphology of the various animal species. Oblate medusae have been …

In this paper, we present a theoretical, experimental and numerical study of the dynamics of
cavitation bubbles inside a droplet suspended in another host fluid. On the theoretical side …

Recent studies suggest that vortex ring formation during left ventricular (LV) rapid filling is an
optimized mechanism for blood transport, and that the volume of the vortex ring is an …

In the last decade, attempts at synthesizing artificial cells for studying cell biology or for
biomedical and therapeutic applications have increased dramatically. Yet, a large part of …

We present high-fidelity numerical simulations of expiratory biosol transport during normal
breathing under indoor, stagnant air conditions with and without a facile mask. We …

Starting flow through a nozzle or orifice typically results in the transient formation of a
leading vortex ring and trailing jet. Experiments are conducted to investigate the dynamics of …
