Subharmonic instability of large-scale wavy structures in two-dimensional channels
An-Xiao Han, Peng-Yu Duan, Ming-Ze Ma +1
A particular interest on two-dimensional turbulence is the inverse energy cascade from small to large sales, which leads to an energy condensation accompanied by the formation of l…
On how walls shape dissipation intermittency
Peng-Yu Duan, Xi Chen, Katepalli R. Sreenivasan
Intermittency of energy dissipation has long been studied via high-order moments in homogeneous and isotropic turbulence, but not much where the boundary effects are explicitly inc…
Multiscale circulation in wall-parallel planes of turbulent channel flows
Peng-Yu Duan, Xi Chen, Katepalli R. Sreenivasan
Wall turbulence consists of various sizes of vortical structures that induce flow circulation around a wide range of closed Eulerian loops. Here we investigate the multiscale prope…
Bounded dissipation law and profiles of turbulent velocity moments in wall flows
Xi Chen, Katepalli R. Sreenivasan
Turbulent wall flows offer the most direct means for understanding the effects of boundaries and viscosity on turbulent fluctuations. Available data on mean-square fluctuations in…
