SUMMARY:From Olympic rowing to gunwale bobbing: Wave drag and wave thrust 
 phenomena - Graham Benham\, U. Oxford
DTSTART:20221028T150000Z
DTEND:20221028T160000Z
UID:TALK183638@talks.cam.ac.uk
CONTACT:Prof. Jerome Neufeld
DESCRIPTION:In this talk I will discuss different wave phenomena associate
 d with motion on the surface of water. I’ll start with some previous wor
 k on waves in Olympic rowing and how to reduce drag\, either by tuning the
  shape of the boat\, or by exploiting hysteresis patterns in regions of sh
 allow water. Then I’ll talk about current research within the theme of w
 ave-driven propulsion\, i.e. how thrust can be generated from surfing the 
 gradients of a self-generated wave-field. This phenomenon occurs across a 
 wide range of scales\, from tiny walking droplets in a vibrating bath\, to
  jumping up and down on the sides of a canoe to drive it forwards\, also k
 nown as gunwale bobbing.
