Paul Baisamy is a Ph.D. Candidate under the supervision of Dr. Francesco Giorgio-Serchi and Prof. Adam A Stokes , Soft Systems Research Group, University of Edinburgh, Edinburgh, UK.
His research focuses on understanding and exploiting the fluid dynamics phenomena at play in shape varying underwater systems. In particular, he is interested in propulsive efficiency enhancement and in developing underwater and medical robotic applications inspired by animals such as the squid or the jellyfish. Prior to that, he worked as a R&D Engineer on the development of nature inspired pulsatile Left Ventricular Assist Devices (LVAD) to treat patients suffering from advanced heart failure. He holds a Mechanical Engineering degree with a speciality in Integrated Design from the University of Technology of Compiegne, France.
Dynamics of bio-inspired pulse jet systems
Pulse jet propulsion is an underwater locomotion technique achieved by periodically expanding and contracting an elastic hollow cavity which, in turn, drives the ingestion and ejection of ambient fluid. This locomotion method is used on a wide range of scales by a variety of sea dwelling animals, notably by insect-sized swimmers such as the pigmy squid or the bell-shaped jellyfish. Less known, one insect in its nymph state, the dragonfly, also rely on this locomotion method. Some of the animals using pulse jet propulsion have shown to excel in minimizing metabolic energy consumption. In a constant quest for energy consumption reduction, how can we take inspiration from these animals to design pulsatile energy efficient systems? What are the leading mechanical and hydrodynamic parameters driving the dynamic of pulse jet propulsion?
