Description: Joint Mechanical Engineering (MNE) and Engineering and Applied Sciences (EAS) SEMINAR
DATE:
November 20, 2020
TIME:

SPEAKER:
Dr. Banafsheh Seyed-Aghazadeh, Assistant Professor
Department of Mechanical Engineering, UMass Dartmouth
TOPIC:
Fluid-Structure Interactions: From Fundamentals to Applications in Biomimetic Sensor Design and Energy Harvesting
ABSTRACT:
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 systems, from aeolian harps to power transmission lines, towing cables, undersea pipelines, drilling risers and mooring lines used to stabilize offshore floating platforms. The majority of studies on FIV have focused on symmetric systems, in which the structure, its geometry, its boundary conditions, and the incoming flow are symmetric. However, in many real-world applications, FIV occurs in asymmetric systems. In the first part of the presentation, I will talk about fundamentals of flow-induced vibration of structures with broken symmetry, and I will discuss how structure's response is affected through different asymmetries introduced into the system. In the second part of my talk, I will discuss how flow-induced vibration-based energy harvesting from external sources available in the environment, such as wind or marine currents, has the potential to be used in novel energy harvesting techniques. I will also discuss how my research findings can lay the foundation for future research projects in the area of biomimetic fluidic sensor design with applications in ocean sensing.
BIO:
Banafsheh Seyed-Aghazadeh is an assistant professor at the Mechanical Engineering department and the director of Laboratory for Fluid-Structure Interactions Studies (fsilab.sites.umassd.edu) at University of Massachusetts, Dartmouth. Before joining UMassD, she was the James R. Myers Endowed assistant professor at Miami University and prior to that a postdoctoral research associate and a lecturer at the department of Mechanical and Industrial Engineering at the University of Massachusetts, Amherst (UMass). She received her PhD from University of Massachusetts, Amherst, and master's and bachelor's degrees from University of Tabriz, Iran, all in Mechanical Engineering. Her research focuses on experimental Fluid-Structure Interactions (FSI), which combines fluid dynamics research with ideas on advanced nonlinear dynamics.
