Non-normal energy amplifications in stratified turbulent channels
Carlo Cossu
The influence of stable and unstable stratification on the amplification of coherent structures in turbulent channel flows is investigated by computing the linear response to stoch…
Evaluation of tilt control for wind-turbine arrays in the atmospheric boundary layer
Carlo Cossu
Wake redirection is a promising approach designed to mitigate turbine-wake interactions which have a negative impact on the performance and lifetime of wind farms. It has recently…
Replacing wakes with streaks in wind turbine arrays
Carlo Cossu
Wind turbine wakes negatively impact downwind turbines in wind farms reducing their global efficiency. The reduction of wake-turbine interactions by actuating control on yaw angles…
Self-sustained large-scale motions in the asymptotic suction boundary layer
Sajjad Azimi, Carlo Cossu, Tobias M. Schneider
Large-scale motions, also known as superstructures, are dynamically relevant coherent structures in a wall-bounded turbulent flow, that span the entire domain in wall-normal direct…
On the relevance of Reynolds stresses in resolvent analyses of turbulent wall-bounded flows
Pierluigi Morra, Onofrio Semeraro, Dan S. Henningson +1
The ability of linear stochastic response analysis to estimate coherent motions is investigated in turbulent channel flow at friction Reynolds number Re = 1007. The analysis is…
Travelling-wave solutions bifurcating from relative periodic orbits in plane Poiseuille flow
Subhendu Rawat, Carlo Cossu, François Rincon
Travelling-wave solutions are shown to bifurcate from relative periodic orbits in plane Poiseuille flow at Re = 2000 in a saddle-node infinite period bifurcation. These solutions c…
