Abstract-
This talk will present progress toward an understanding of the
physical mechanisms of biological fluid transport. Specifically, the topic
of unsteady fluid transport by pulsed jets will be addressed. Experiments
enable quantification of the contributions from vortex ring formation,
entrainment, and added-mass in the transport process. Models of the
salient fluid mechanics that incorporate biologically-relevant, unsteady
effects are developed with sufficient generality to allow application to
systems as varied as the squid mantle and the human heart.
