报告内容摘要：
The Flux Reconstruction (FR) approach, which was first developed by Huynh in 2007[1], is a mathematical framework for developing nodal unstructured high-order schemes based the governing system in differential form. As such, unlike many of its unstructured high-order counterparts, the FR approach does not require quadrature rules to be implemented and employed. Consequently FR schemes are particularly straightforward to implement in an efficient manner. It is hoped that the simple and efficient nature of FR schemes will facilitate adoption of unstructured high-order methods amongst a wider community of fluid dynamicists. In this seminar I will discuss various aspects of FR schemes. Particular attention will focus on a new class of energy-stable FR schemes [2]. The theory behind these new schemes will be presented, along with details of how they can be implemented efficiently for graphical processing units. Finally, application areas for the new methods will be discussed, and their ability to perform affordable yet accurate Large Eddy Simulations (LES) of real world turbulent flows will be assessed. The ability to routinely perform such LES could transform the design process of numerous products, including landing gear configurations, flapping wing micro air vehicles, and rotorcraft.
报告人简介：
Dr. Vencent received his Bachelor degree in 2005 from Department of Physics, Imperial College, and Doctor degree in 2009 from Department of Aeronautics, Imperial College. During 2009-2011, he worked as Postdoctoral scholar with Prof. Antony Jameson at Stanford University, USA. Since 2011 he became a lecture at Department of Aeronautics, Imperial College, UK. Dr. Vencent is interested in the development of novel numerical methods and their application to solve hitherto intractable fluid flow problems in various areas of science and engineering. He is particularly interested in theoretical aspects of high-order numerical methods for unstructured grids, as well as their implementation for modern (many core) hardware platforms.
