Abstract: Wall-modeled large-eddy simulation (WMLES) of turbulent channel flow is performed to evaluate its predictive capability for near-wall turbulent fluctuations, coherent structures, and turbulence kinetic energy (TKE) budget—aspects that have received relatively little attention in previous… read more here.

Abstract: We derive a universal bound on the large-deviation functions of particle currents in coherent conductors. This bound depends only on the mean value of the relevant current and the total rate of entropy production required… read more here.
