Hierarchical construction of higher-order exceptional points
Q. Zhong, J. Kou, S. K. Ozdemir +1
The realization of higher-order exceptional points (HOEPs) can lead to orders of magnitude enhancement in light-matter interactions beyond the current fundamental limits. Unfortuna…
Comparisons of Two Reduced-Order Models for Linearized Unsteady Aerodynamic Identification
Jiaqing Kou, Weiwei Zhang
This paper compares the performance of two unsteady aerodynamic reduced-order models (ROMs), namely linear Volterra series and the autoregressive with exogenous input (ARX) model,…
Machine learning methods for turbulence modeling in subsonic flows over airfoils
Weiwei Zhang, Linyang Zhu, Yilang Liu +1
Reynolds-Averaged Navier-Stokes(RANS) method will still play a vital role in the following several decade in aerospace engineering. Although RANS models are widely used, empiricism…
Mode Multigrid - A novel convergence acceleration method
Yilang Liu, Weiwei Zhang, Jiaqing Kou
This paper proposes a mode multigrid (MMG) method, and applies it to accelerate the convergence of the steady state flow on unstructured grids. The dynamic mode decomposition (DMD)…
