    报告题目:Flow-Induced Vibrations of Spheres 

    摘要:The sphere is the important generic three-dimensional bluff body geometry widely used in aero- and hydrodynamics, and was employed by Galileo to demonstrate that acceleration due to gravity was independent of mass. However, little was known of the flow-induced vibrations of spheres in motion relative to fluid flows until the pioneering study by Govardhan & Williamson in 1997. In this presentation, the rich array of flow-induced vibrations that arise for spheres that have been uncovered in recent times at the FLAIR lab will be discussed. These include the effects of uniform rotation and rotary oscillations, free surfaces, rolling on solid surfaces, and trip rings. Some variations lead to vibration suppression, some to vibration enhancement, and others to a mixture of outcomes for different vibration modes.  Both experimental and computational investigations will be reported.  

    报告人简介:

    Prof Kerry Hourigan has an extensive research and industrial background in experimental and computational fluid dynamics, having researched at the NASA Jet Propulsion Laboratory, the California Institute of Technology, the CSIRO and Monash University, as well as numerous visiting professorships in France and Japan. He recently directed the Division of Biological Engineering at Monash University, establishing major laboratories and facilities for bio engineering and developing multi-discipline collaborations between engineers, biologists, and computer scientists, and the translation of the research to industry. He is a Professor in the Department of Mechanical and Aerospace Engineering at Monash University and researches in the Fluids Laboratory for Aeronautical and Industrial Research (FLAIR), with joint PhD supervision with IIT Bombay. He is an Associate Editor of the Journal of Fluids and Structures. A theme of his research over several decades has been bluff body flows, ranging from planetary formation to vehicular aerodynamics to bioreactors.
