An inviscid model study of sandstorm in unstably stratified atmospheric boundary layer
Chenyue Xie, Xiangming Xiong, Jianjun Tao
According to field observations, the atmospheric boundary layer is usually unstably stratified before a dust and sandstorm, the particle-laden turbulent gravity current with an ext…
Energy stability of the Charney-DeVore quasi-geostrophic equation for atmospheric blocking
Zhi-Min Chen, Xiangming Xiong
Charney and DeVore [J. Atmos. Sci. 36 (1979), 1205-1216] found multiple equilibrium states as a consequence of bottom topography in their pioneering work on the quasi-geostrophic b…
Artificial neural network approach for turbulence models: A local framework
Chenyue Xie, Xiangming Xiong, Jianchun Wang
A local artificial neural network (LANN) framework is developed for turbulence modeling. The Reynolds-averaged Navier-Stokes (RANS) unclosed terms are reconstructed by artificial n…
The Unified Transition Stages in Linearly Stable Shear Flows
Jianjun Tao, Xiangming Xiong
Abrupt transition to turbulence may occur in pipe and channel flows at moderate flow rates, an unexpected event according to linear stability theory, and has been an open problem i…
Extended localized structures and the onset of turbulence in channel flow
Jianjun Tao, Bruno Eckhardt, Xiangming Xiong
In this letter, it is shown numerically that in plane Poiseuille flow and before the threshold of equilibrium turbulence defined by the directed-percolation universality class, a s…
