A wall model based on neural networks for LES of turbulent flows over periodic hills
Zhideng Zhou, Guowei He, Xiaolei Yang
In this work, a data-driven wall model for turbulent flows over periodic hills is developed using the feedforward neural network (FNN) and wall-resolved LES (WRLES) data. To develo…
Clustering and relative velocities of heavy particles under gravitational settling in isotropic turbulent flows
Guodong Jin, Guo-Wei He
Spatial clustering and intermittency in the relative velocity of heavy particles of the same size settling in turbulent flows can be strongly affected by gravity. We present a mode…
Lift Enhancement by Dynamically Changing Wingspan in Forward Flapping Flight
Shizhao Wang, Xing Zhang, Guowei He +1
Stretching and retracting wingspan has been widely observed in the flight of birds and bats, and its effects on the aerodynamic performance particularly lift generation are intrigu…
Temporal decorrelations in compressible isotropic turbulence
Dong Li, Xing Zhang, Guowei He
Temporal decorrelations in compressible isotropic turbulence are studied using the space-time correlation theory and direct numerical simulation. A swept-wave model is developed fo…
Statistics of Dissipation and Enstrophy Induced by a Set of Burgers Vortices
Guowei He, Shiyi Chen, Robert. H. Kraichnan +2
Dissipation and enstropy statistics are calculated for an ensemble of modified Burgers vortices in equilibrium under uniform straining. Different best-fit, finite-range scaling exp…
