Turbulence near initial conditions
K. Steiros
Abstract
Past studies have shown that decaying homogenous turbulence exhibits nonclassical properties near the initial conditions that gave rise to it (e.g. a turbulence grid in laboratory settings, or a numerical forcing in simulated turbulence). Here, we explore these nonclassical properties using a combination of numerical and theoretical work. A novel cascade picture for turbulence near initial conditions is also proposed.
