| Abstract | ABSTRACT: Liquid fluid drops tend to spherical shapes under equilibrium configurations. When perturbed, these fluid droplets oscillate, representing the competition between the inertia and capillary action of the fluid drop. The qualitative behavior of these drops is similar to the free interfaces of the the contact zone of the Planar-flow Melt Spinning device used to continuously cast sheets of metal. In collaboration with scientists from Germany, we have analytically modeled the capillary oscillations of coupled spherical cap droplets. We have also learned about the limitations of current numerical techniques of free interface problems in fluid mechanics. In addition to these academic achievements, we have learned a great deal about the German academic system, culture and formed a productive collaboration with a foreign scientist. |

| Bio | Joshua Bostwick received a B.S.E. degree in Civil Engineering & Mechanics with a minor in Mathematics and a B.S. in Physics from the University of Wisconsin-Milwaukee in 2005. Currently, he is working on his PhD in Theoretical and Applied Mechanics from Cornell University under the direction of Dr. Paul Steen. His research interests include capillary oscillations, free interface dynamics, stability theory, symmetry methods applied to dynamical systems and engineering education. Dr. Paul H. Steen has been at Cornell since 1982. He is a Professor in the School of Chemical and Biomolecluar Enginerering, with field affiliations in Applied Mathematics and Theoretical and Applied Mechanics. His research is in the area of dynamics and stability of fluid systems with interfaces. Current focus is on shape-changes of gas/liquid and liquid/liquid interfaces and stability issues arising in the continuous casting of thin sheets of metal. He is a fellow of the American Physical Society (1996) and has been active in APS/Division of Fluid Dynamics affairs as chair of the Fluid Dynamics Prize Committee, and as member of the Executive, Program, Publications and Frenkiel Award Committees. He has co-edited “A Gallery of Fluid Motionâ€, a DFD-APS project published by Cambridge University Press. He is an Associate Editor of the Journal of Fluid Mechanics. He has more than 60 journal publications and has edited several books. Prior to coming to Cornell, Steen received his PhD from The Johns Hopkins University in 1981 and held post-doctoral position in Chemical Engineering at Stanford University, after having completed undergraduate degrees in Engineering and English Literature at Brown University. At Cornell, he has served as Director of Graduate Studies for Chemical Engineering. He has received an Alexander von Humboldt Fellowship and has been a Senior Guest Scientist at the Forschungzentrum Karlsruhe, Germany. |
