Relation between the moments of longitudinal velocity derivatives and of dissipation in turbulence
Ping-Fan Yang, Haitao Xu, Alain Pumir
In homogeneous and isotropic turbulence, measurements of the longitudinal velocity derivative, , make it possible to estimate a surrogate of the rate of energy diss…
Analytical estimations of edge states and extended states in large finite-size lattices
Huajie Song, Haitao Xu
The bulk boundary correspondence, one of the most significant features of topological matter, theoretically connects the existence of edge modes at the boundary with topological in…
The contribution of dilatational motion to energy flux in homogeneous compressible turbulence
Chensheng Luo, Le Fang, Jian Fang +3
We analyze the energy flux in compressible turbulence by generalizing the exact decomposition recently proposed by Johnson (Phys. Rev. Lett., vol. 124, 2020. 104501) to study incom…
Low-order moments of the velocity gradient in homogeneous compressible turbulence
PingFan Yang, Jian Fang, Le Fang +2
We derive from first principles analytic relations for the second and third order moments of the velocity gradient mij = dui/dxj in compressible turbulence, which generalize known…
Unstable dynamics of solitary traveling waves in a lattice with long-range interactions
H. Duran, H. Xu, P. G. Kevrekidis +1
In this work we revisit the existence, stability and dynamics of unstable traveling solitary waves in the context of lattice dynamical systems. We consider a nonlinear lattice of a…
