Design of the wavy wall in a partially heated channel using CFD simulations and human-assisted Bayesian optimization
Piotr Kamiński, Karol Wawrzak, Yiqing Li +2
This study explores heated wavy wall shape design in channel flow using machine learning, aiming to minimize temperature variation () while limiting pressure loss (). A co…
Origin and control of pseudo-rotating spiral jets
Karol Wawrzak, Yiqing Li, Bernd R. Noack +1
Active flow control (AFC) methods for jet-type flows have been extensively explored since the 1970s. Spectacular examples demonstrating the AFC power and the beauty of fluid mechan…
Experimental jet control with Bayesian optimization and persistent data topology
Johann Moritz Reumschüssel, Yiqing Li, Philipp Maximilian zur Nedden +3
This study experimentally optimizes the mixing of a turbulent jet at with the surrounding air by targeted shear layer actuation. The forcing is composed of superposed ha…
Deep reinforcement transfer learning for active flow control of a 3D square cylinder under state dimension mismatch
Lei Yan, Gang Hu, Wenli Chen +1
This paper focuses on developing a deep reinforcement learning (DRL) control strategy to mitigate aerodynamic forces acting on a three dimensional (3D) square cylinder under high R…
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…
