The prediction of extreme uncertainty-production events in three-dimensional Navier-Stokes turbulence
Jin Ge, Joran Rolland, John Christos Vassilicos
We investigate the exponential growth of uncertainty energy in 3D Navier-Stokes turbulence, emphasising the intermittent and highly localized amplification/production of uncertaint…
Navier-Stokes-driven analysis of mean and fluctuating wall shear stress in turbulent channel flow
Le Yin, Yongyun Hwang, John Christos Vassilicos
We propose a Navier-Stokes-driven analysis of the mean and fluctuating wall shear stress (WSS) applied to turbulent channel flow data from direct numerical simulations at friction…
Passive scalar cascade in the intermediate layer of turbulent channel flow for
Emanuele Gallorini, Shingo Motoki, Genta Kawahara +1
Similarities and differences between Kolmogorov scale-by-scale equilibria/non-equilibria for velocity and scalar fields are investigated in the intermediate layer of a fully develo…
Eulerian-Lagrangian scaling of the Lyapunov exponent in homogeneous turbulence
Jin Ge, Joran Rolland, John Christos Vassilicos
We present a heuristic derivation of the maximal Lyapunov exponent of homogeneous turbulence which yields two new relations, a sweeping relation and the scaling of the uncertai…
The interscale behaviour of uncertainty in three-dimensional Navier-Stokes turbulence
Jin Ge, Joran Rolland, John Christos Vassilicos
We derive the scale-by-scale uncertainty energy budget equation and demonstrate theoretically and computationally the presence of a self-similar equilibrium cascade of decorrelatio…
The production of uncertainty in three-dimensional Navier-Stokes turbulence
Jin Ge, Joran Rolland, John-Christos Vassilicos
We derive the evolution equation of the average uncertainty energy for periodic/homogeneous incompressible Navier-Stokes turbulence and show that uncertainty is increased by strain…
