Meet USC
Wed, Jan 28, 2009
Viterbi School of Engineering Undergraduate Admission
Workshops & Infosessions
This half day program is designed for prospective freshmen and family members. Meet USC includes an information session on the University and the Admission process; a student led walking tour of campus and a meeting with us in the Viterbi School. Meet USC is designed to answer all of your questions about USC, the application process and financial aid.Reservations are required for Meet USC. This program occurs twice, once at 9:00 a.m. and again at 1:00 p.m. Please visit http://www.usc.edu/admission/undergraduate/visit/meet_usc.html to check availability and make an appointment. Be sure to list an Engineering major as your "intended major" on the webform!

Vortex Induced Vibrations

Conferences, Lectures, & Seminars
A. Leonard Theodore von Kármán Professor of Aeronautics,
EmeritusGraduate Aeronautical LaboratoriesCalifornia Institute of TechnologyPasadena, CA Vortex shedding from a bluff body can impose significant, time-dependent forces on the body. If the body is freely oscillating, the amplitude of the resulting vibration can lead to disastrous consequences in some instances or, on the plus side, can be the essence of a proposed power generation scheme. The amplitude and frequency of the motion depends on the shape of the body and on four parameters: nondimensional mass, damping coefficient, spring constant or stiffness, and Reynolds number. In some cases, the expected resonant behavior occurs when the vortex shedding frequency is close to the natural vibration frequency of the mechanical system and the damping is low. But there are important ranges of these parameters that yield contrary results. Laboratory and computational experiments of flow past a freely oscillating circular cylinder will be discussed along with a new theoretical approach that requires only three parameters: effective stiffness, damping, and Reynolds number, and takes the mystery out of some of the mysterious results reported in the literature.
