A Perspective on Industrial Large Eddy Simulation Using High-Order Methods

Z.J. Wang (王志坚)

Spahr Professor of AerospaceEngineering

University of Kansas, Lawrence,Kansas 66045

Abstract：The promise of large eddy simulation (LES) has been known for manydecades, and its application to real world flow problems, however, has beenhindered by its computational cost. Although the Reynolds-averaged Navier-Stokes(RANS) approach has gained wide acceptance in industry, many applications stillcall for scale-resolving simulations such LES or hybrid RANS/LES approaches.

Inthis talk, I will highlight some of our efforts in pushing high order methodstowards turbo-machinery and aero-acoustic applications:

•High order space-discretizationcapable of handling unstructured meshes

•Efficient and scalable timeintegration

•Overset and sliding meshalgorithms

•Parallel implementation onextreme-scale CPU/GPU computers

Inaddition, I will describe the application of the high-order LES tool, hpMusic,in computing vortex-dominated turbulent flows in turbomachinery andaero-acoustic noise computation. The talk will conclude with possible futurework.

Short Bio: Z.J. Wang, Spahr Professor of Aerospace Engineering, at the Universityof Kansas (KU), received his BS from National University of Defense Technology,and Ph.D. from the University of Glasgow. Then he conducted post-doctoralresearch in Glasgow and Oxford before joining CFD Research Corporation inHuntsville, Alabama as a Research Engineer, and then a Technical Fellow. In2000, he joined the faculty of Mechanical Engineering at Michigan StateUniversity, and in 2005, joined the faculty of Aerospace Engineering at IowaState University. In 2012 he came to KU’s Aerospace Engineering Department, andserved as the Chair for 5 years. Dr Wang has edited a book, written many reviewarticles, (co-)organized multiple International Workshops on High-Order CFD Methods,and advocated their applications for real world flow problems. He is veryactive in AIAA, served as an Associate Editor of the AIAA Journal from 2006 to2016, and is an AIAA Fellow.
