TITLE:  Analytical and Computational Models for Instability Analysis of Some Fluid-Structure Interaction Problems

Time：2019/10/14（Mon.）13:30—15:30

Add.：The main meeting room of SoME （North Building 2- R344 ）

Rapporteur：Professor Sheldon Wang, Ph.D.,P.E

ABSTRACT：

In this talk, a few FSI problems will be studied with both computational and analytical methods. In particular, analytical models for a Helmholtz attenuator and parametric instability analysis with Bolotin’s approach and Monodromy matrix for FSI systems with periodic perturbations along with full fledged computational approaches will be presented. Physical insights will be derived from the instability diagram and the transition points for buckling and flutter instabilities. Some suppression mechanisms are also presented for the reduction of flow-induced vibrations.

INTRODUCTION OF Rapporteur：

Dr. Sheldon (Xiaodong) Wang is a tenured Full Professor in McCoy School of Engineering at Midwestern State University. He received his B.S. in Naval Architecture and Ocean Engineering from Shanghai Jiao Tong University (1988), and his M.S. in Ocean Engineering (1993) and Ph.D. in Applied Mechanics (1995) from MIT. Subsequently, he has worked in the Institute of Paper Science and Technology (currently, Georgia Tech), Polytechnic University (currently. New York University), and NJIT as a faculty member before joining MSU in 2009 as the Chair of McCoy School of Engineering. Dr. Wang's research interests include computational fluid and solid mechanics, fluid-solid interactions, quantitative modeling of biological systems, and dynamical systems.
