The promise of large eddy simulation (LES) has been known for many decades, and its application to real-world flow problems, however, has been hindered by its computational cost. Although the Reynolds-averaged Navier-Stokes (RANS) approach has gained wide acceptance in industry, many applications call for LES. In this talk, I will highlight our efforts to improve the efficiency, accuracy, and robustness of LES in
- High-order space-discretization
- Efficient and scalable time integration on CPU/GPU clusters
- Wall-resolved and wall-modeled LES
In addition, I will describe the application of the high-order LES tool, hpMusic, in computing vortex-dominated turbulent flows including the benchmark problems in the AIAA High-Lift Prediction Workshops, and turbomachinery applications. The talk will conclude with possible future work.
Z.J. Wang is Spahr Professor of Aerospace Engineering, at the University of Kansas (KU). His research interests include adaptive high-order methods, large eddy simulation, and high-performance computing on CPU and GPU clusters. Dr Wang has edited a book, written many review articles, (co-)organized multiple International Workshops on High-Order CFD Methods. High order LES tools developed by his group have been used by industry to tackle challenging flow problems on some of the fastest supercomputers including Summit and Frontier. He has published over 280 journal and conference papers on CFD algorithms and applications. He is a Fellow of AIAA.
This seminar counts towards the ME 6000 seminar requirement for Mechanical Engineering graduate students.
