Seminar: Bioinspired Propulsion and Sensing Systems Enabling Next Generation Underwater Vehicles
Zoom Meeting ID______ 944 3679 2959 Passcode: ore792Michael Krieg, PhD Assistant Professor Department of Ocean & Resources Engineering University of Hawai'i at Mānoa Even the most robust and sophisticated underwater robots pale in comparison to the performance of the ocean’s natural inhabitants, as many of which seem to traverse turbulent environments with ease and also demonstrate effective long range migration patterns. This talk analyzes a novel propulsion mechanism inspired by the locomotion of squid and jellyfish; whereby, finite fluid jets are ejected from a flexible internal cavity in a periodic fashion. Vortex ring formation, which is associated with expelled jets starting from rest, causes the thrust associated with this
MS Plan B Defense: Using Differential Pressure sensor arrays to identify wake structures created by a heaving and pitching foil
zoom See link in announcementGary Glass Master’s Student Department of Ocean and Resources Engineering University of Hawai’i at Mānoa This defense will be held via zoom Meeting ID: 936 1860 0974 Passcode: GaryMS https://hawaii.zoom.us/j/93618600974 Inspired by the lateral line sensory system of fish, sensor arrays distributed over the surface of underwater vehicles can be used to sense the fluid surroundings. While previous studies have used such a system to compensate for fluid forces acting on a vehicle, here the goal is to use the distributed pressure sensors to detect nearby fin wake patterns, as is done by schooling fish. This study aims to design
