The streamwise evolution and multi-scale interactions of energy-eddies in incompressible zero pressure gradient (ZPG) turbulent boundary layers (TBLs) is investigated by removing these eddies at the inflow of a ZPG-TBL direct numerical simulation (DNS) and examining the turbulent kinetic energy and Reynolds Shear stress transport using the spanwise spectral decomposition approach introduced by Kawata and Alfredson (2018).
