MIE Engineering Leadership Lecture Presentation: Fundamental Fluid Dynamics And the Olympic Swimming Movement by Professor Timothy Wei, Dean, College of Engineering, University of Nebraska at Lincoln

Abstract: The world of competitive swimming is dynamic. Swimmers today are bigger, stronger and faster than they ever have been. The training regimen of an elite athlete includes not only endless practice of his or her skills, but also a carefully planned diet, strength and endurance training, and hours of mental preparation. Within this framework, we have teamed with USA Swimming to develop advanced, fluid dynamics based training and analysis tools for current and future Olympic swimmers. The focus of this presentation will be on the objectives, methodologies and outcomes of measurements of flow around swimmers. Movies of PIV flow measurements and time resolved force measurements around swimmers, including Beth Botsford and Megan Jendrick, 1996 and 2000 Gold Medalists in the 100 meter back and 100 meter breast, respectively, will be presented. Work with Ariana Kukors, 2012 Olympian, 2009 World Championships gold medalist and world record holder in the 200 IM. In addition, the measurement technique has recently been applied to dolphins. Data from those experiments will be shown as well.  

Biographical Sketch: Timothy (Tim) Wei is the Richard L. McNeel Professor and Dean of Engineering at the University of Nebraska – Lincoln. Prof. Wei received a B.S. from Cornell in 1980 and an M.S. from Lehigh in 1982, both in Mechanical Engineering. In 1987, he was awarded a Ph.D. in Aerospace Engineering from Michigan. After a brief Post-doctoral appointment at Michigan, Prof. Wei joined the faculty of Mechanical & Aerospace Engineering at Rutgers in 1987. In 2006, Prof. Wei joined RPI as Head of Mechanical, Aerospace and Nuclear Engineering. He moved to the Nebraska in 2011 to become the Dean of Engineering. Prof. Wei has held visiting faculty appointments at the Naval Surface Warfare Center (Carderock, MD), MIT and the Tampere University of Technology (Tampere, Finland). He is a Fellow of the American Society of Mechanical Engineers, Institution for Mechanical Engineering and the American Physical Society. Prof. Wei’s research interests lie in coupling fundamental fluid dynamics experiments with critically important technologies. One of his favorite projects has been making flow measurements around elite swimmers through a collaboration with the US Olympic Swimming Movement.
