Joint Mechanical Engineering and Engineering & Applied Science (MNE-EAS) Seminar

When: Friday, March 6, 2015
2:00 PM - 3:00 PM
Where: Textiles Building 101E
Description: Joint MNE-EAS Seminar


Friday, March 6th 2015
2:00 p.m. - 3:00 p.m.
Textile Building, Room 101E


SPEAKER:
Dr. Yahya Modarres-Sadeghi, Assistant Professor
Mechanical & Industrial Engineering Department at
UMass Amherst


TOPIC:
Fluid-Structure Interactions:
From Fundamentals to Applications in Offshore
Wind Energy Research


ABSTRACT:
When a flexible or flexibly-mounted structure is in contact with flow, it could deform or oscillate due to the fluid forces. The deformation or oscillation of the structure changes the fluid forces, which in turn result in a different structural response. This constitutes a fluid-structure interaction (FSI) problem. In a floating wind turbine, many examples of FSI are observed. Large wind turbine blades, which are ideal for offshore wind turbines, are susceptible to various flow- induced dynamical instabilities. A spar-type floating turbine can undergo vortex-induced vibration (VIV). In this talk I will show some recent results on flow-induced instabilities of wind turbine blades, and I will discuss VIV of a spar buoy, modeled after one of the existing large- scale floating wind turbines. I will discuss how some fundamental studies on FSI problems are critical in understanding the observed phenomena in floating wind turbines.
