In this paper, direct numerical simulations (DNS) are presented to understand the effects of the inlet conditions on the turbulent energy decay rate of isotropic turbulence. A perfect control of the inlet conditions cannot be achieved in realistic simulations reproducing the effects of a solid grid,...
