Abstract: A current breakthrough in computational fluid dynamics (CFD) is the emergence of adaptive high-order (order > 2) methods. The leader is the discontinuous Galerkin (DG) method, amongst several other methods including the multi-domain spectral, spectral volume (SV), spectral difference (SD) methods. Recently, the correction procedure via reconstruction (CPR) formulation was developed to unify all the methods under a single framework. All these methods possess the following properties: k-exactness on arbitrary grids, and compactness, which is especially important for parallel computing on clusters of CPUs and GPUs. In this talk, I will describe the CPR formulation, and explain its connection to the DG, SV and SD methods. In addition, the application of high-order methods to compute transitional flow over a SD7003 wing and flow over flapping wings will be presented. The talk will conclude with several remaining challenges in the research on high-order methods. 

About the Speaker:

Zhi-Jian Wang, Wilson Professor of Engineering and Director of Computational Fluid Dynamics (CFD) Center at the Iowa State University (ISU), received his Ph.D. in Aerospace Engineering from the University of Glasgow in 1990. Then he conducted post-doctoral research in Glasgow and Oxford before joining CFD Research Corporation in Huntsville, Alabama in 1991 as a Research Engineer, and later becoming a Technical Fellow. In 2000, he joined the faculty of Michigan State University as an Associate Professor of Mechanical Engineering. In 2005 he returned to Aerospace Engineering at ISU. He has been active in CFD research since early 1990es with over 160 journal and conference publications. His research areas include adaptive high-order methods for the Navier-Stokes equations, algorithm and flow solver development for structured and unstructured, overset and adaptive Cartesian grids, computational aeroacoustics and electromagnetic, large eddy simulation of transitional and bio-inspired flow problems, high performance computing on CPU and GPU clusters, geometry modeling and grid generation. He was an invited lecturer of the von Karman Institute Lecture Series on High-Order CFD Methods in 2005 and 2008. He is an Associate Fellow of AIAA, and an Associate Editor of the AIAA Journal. He was awarded the degree of Doctor of Science in Engineering by the University of Glasgow in 2008, and a Distinguished Service Award by the Fluid Dynamics Technical Committee of AIAA in 2010.
