Turbulent separation control with a tilted wavy wall: a promising approach for energy savings in aerodynamic systems
Piotr KamiÅski, Artur Tyliszczak, Witold Elsner +1
Recently, KamiÅski et al. [1] demonstrated that a two-dimensional streamwise waviness with carefully selected amplitude and period can be effectively used in postponement of a flo…

Jet mixing enhancement with Bayesian optimization, deep learning, and persistent data topology
Yiqing Li, Bernd R. Noack, Tianyu Wang +4
We optimize the jet mixing using large eddy simulations (LES) at a Reynolds number of . Key methodological enablers consist of Bayesian optimization, a surrogate model enhanc…
