Seminar: Fluid-Structure Interactions: From Fundamentals of Flow-induced Vibration to Applications in Energy Harvesting

October 28 @ 3:30 pm - 4:30 pm
Zoom Meeting ID______ 915 4908 5495, Passcode: 486116

Banafsheh Seyed-Aghazadeh, PhD Mechanical Engineering Department, University of Massachusetts, Dartmouth When a flexible or flexibly-mounted structure is placed in fluid flow, it can deform or oscillate. The deformation or oscillation of the structure will result in the change of flow forces, which in turn will result in the change of the structure’s deformation or oscillation. This is called a Fluid-Structure Interactions (FSI) problem and the oscillation is called Flow-Induced Vibration (FIV). FIV has significant implications for a number of physical…

Experiments and interpretation of ice-induced vibrations of offshore structures

November 4 @ 9:00 am - 10:00 am
Zoom Meeting ID______ 968 0761 9339, Passcode: 737255

Dr. Torodd Nord Associate Professor Department of Ocean Operations and Civil Engineering Norwegian University of Science and Technology (NTNU) When drifting sea ice interacts with a structure, it may result in structural vibrations hence ice-induced vibration.  With the potential to harm the structural integrity, secondary installations and operational safety, ice-induced vibration is an important problem that needs to be addressed in structural design. Since the first deployment of Arctic offshore platforms in Cook Inlet, Alaska in 1960s, extensive measurement campaigns…
