Effect of filter kernel on scale-energetics of near-wall turbulent structures
Daniel Feldmann, Mohammad Umair, Marc Avila +1
Inter-scale energy fluxes, , are widely used as a diagnostic tool to analyse energy transfer across length scales, , in turbulence data. Here, we investigate how the cho…

Taylor rolls on tour: Slow drift of turbulent large-scale structures in flows with continuous symmetries
Daniel Feldmann, Marc Avila
In Rayleigh-Benard convection and Taylor-Couette flow cellular patterns emerge at the onset of instability and persist as large-scale coherent structures in the turbulent regime. T…
