Lyapunov exponents and Lagrangian chaos suppression in compressible homogeneous isotropic turbulence
Haijun Yu, Itzhak Fouxon, Jianchun Wang +4
We study Lyapunov exponents of tracers in compressible homogeneous isotropic turbulence at different turbulent Mach number and Taylor-scale Reynolds number . We demonst…
Fourier neural operator for real-time simulation of 3D dynamic urban microclimate
Wenhui Peng, Shaoxiang Qin, Senwen Yang +3
Global urbanization has underscored the significance of urban microclimates for human comfort, health, and building/urban energy efficiency. They profoundly influence building desi…
Departure from the statistical equilibrium of large scales in three-dimensional hydrodynamic turbulence
Mengjie Ding, Jin-Han Xie, Jianchun Wang
We study the statistically steady states of the forced dissipative three-dimensional homogeneous isotropic turbulence at scales larger than the forcing scale in real separation spa…
Long-term predictions of turbulence by implicit U-Net enhanced Fourier neural operator
Zhijie Li, Wenhui Peng, Zelong Yuan +1
Long-term predictions of nonlinear dynamics of three-dimensional (3D) turbulence are very challenging for machine learning approaches. In this paper, we propose an implicit U-Net e…
Wall cooling effect on spectra and structures of thermodynamic variables in hypersonic turbulent boundary layers
Dehao Xu, Jianchun Wang, Shiyi Chen
The wall cooling effect on the spectra and structures of thermodynamic variables are investigated in hypersonic turbulent boundary layers. The density and temperature can be divide…
Ensemble data assimilation-based mixed subgrid-scale model for large-eddy simulations
Yunpeng Wang, Zelong Yuan, Jianchun Wang
An ensemble Kalman filter (EnKF)-based mixed model (EnKF-MM) is proposed for the subgrid-scale (SGS) closure in the large-eddy simulation (LES) of turbulence. The model coefficient…
Adjoint-based variational optimal mixed models for large-eddy simulation of turbulence
Zelong Yuan, Yunpeng Wang, Xiaoning Wang +1
An adjoint-based variational optimal mixed model (VOMM) is proposed for subgrid-scale (SGS) closure in large-eddy simulation (LES) of turbulence. The stabilized adjoint LES equatio…
