How does an "inverted flag" flap?

Welcome to the beautiful problem of flapping of an inverted flag! In this talk, we will discuss what an inverted flag is, how it can be useful in energy harvesting applications, and what some of the underlying physical mechanisms are that make it work. Among other things, we will identify what initiates flapping and characterize the chaotic behavior that this rich dynamical system can exhibit.

Refreshments available prior to the lecture.

The Everhart Lecture Series is a forum encouraging interdisciplinary interaction among graduate students and faculty, the sharing of ideas about research developments, as well as a space to discuss controversies.  Everhart Lectures allow for the recognition of individual Caltech student's exemplary presentation and research abilities.  Lecturers discuss scientific topics and research topics of concern to graduate students and faculty.

Each Fall, graduate student lecturers are selected to present their ideas as part of a series of lectures.
