The asymptotic behavior of the curvature of material elements in turbulence is investigated using Lagrangian velocity‐gradient time series obtained from direct numerical simulations of isotropic turbulence. Several material‐element ensembles of different initial curvatures and shapes are studied. It is found that, at long times, the (first five) moments of the logarithm of characteristic curvature (C) and shape factor (S) asymptote to values that are independent of the initial curvature or… CONTINUE READING
