MS Plan A Defense: Experimental Investigation of Thin-Walled Cylindrical Cantilever Beams Undergoing Vortex-Induced Vibrations
POST 723 1680 East-West Road, HonoluluClara Encke Master’s Student Department of Ocean and Resources Engineering University of Hawai’i at Mānoa **This defense will be held both in person (POST 723) and over Zoom** Meeting ID: 989 0662 3277 Passcode: ClaraMS https://hawaii.zoom.us/j/98906623277 In this study, we experimentally investigate the dynamic response of three low mass ratio hollow cylindrical cantilever beams experiencing vortex-induced vibrations. We conducted experiments using three polycarbonate cylinders with low mass ratios of 0.761, 0.830 and 0.922, respectively. Motion analysis was performed using two high-speed cameras, and motion tracking was facilitated by UV lights for better image quality. Our findings indicate that the IL:
Seminar: Understanding the Fundamentals of Vortex-induced Vibrations: Research Past, Present and Future
Deniz Gedikli, PhD Assistant Professor Ocean and Resources Engineering Department, University of Hawaii at Manoa Figure 1: Example offshore platforms that undergo VIV The canonical problem of fluid flow across an elastically mounted circular cylinder has been a widely studied problem in fluid mechanics due to the ubiquitous nature of the simple geometry in engineering applications and the resulting complexity of the fluid-structure interaction. In many engineering design and operation applications, it is advantageous to be able to predict fluid-structure interactions such as self-limiting vortex-induced vibrations, since these vibrations can strongly affect fatigue life or operational downtime in a variety
