TL;DR: Parisi-Frisch multifractal theory, suitably extended to the dissipative scales and to the Lagrangian domain, is found to capture the intermittency of velocity statistics over the whole three decades of temporal scales investigated here.

TL;DR: In this paper, the authors reviewed the 2014-2016 JET results in the light of their significance for optimising the ITER research plan for the active and non-active operation, stressing the importance of the magnetic configurations and the recent measurements of fine-scale structures in the edge radial electric.

TL;DR: In this article, the effects of an anisotropic Navier slip-length boundary condition on turbulent channel flow were investigated by direct numerical simulations, where the slip length boundary condition was made direction dependent by specifying the value of the slip lengths independently for the streamwise and spanwise direction.

TL;DR: In this paper, a scan of a rough graphite surface is used as a no-slip boundary in direct numerical simulations of turbulent channel flow, and the effects of the surface filtering on the turbulent flow are investigated by studying a series of surfaces with decreasing level of filtering.

TL;DR: In this article, the authors derived an analytical model for the apparent slip length, the change in drag and the optimum air layer thickness of laminar channel and pipe flow over an idealised superhydrophobic surface, i.e. a gas layer of constant thickness retained on a wall.
