One-point and two-point statistics of homogeneous isotropic decaying turbulence with variable viscosity
Michael Gauding, Luminita Danaila, Emilien Varea
The decay of homogeneous isotropic turbulence in a variable viscosity fluid with a viscosity ratio up to 15 is analyzed by means of highly resolved direct numerical simulations (DN…

High-order structure functions for passive scalar fed by a mean gradient
Michael Gauding, Luminita Danaila, Emilien Varea
Transport equations for even-order structure functions are written for a passive scalar mixing fed by a mean scalar gradient, with a Schmidt number . Direct numerica…

On the self-similarity of line segments in decaying homogeneous isotropic turbulence
Michael Gauding, Lipo Wang, Jens Henrik Goebbert +3
The self-similarity of a passive scalar in homogeneous isotropic decaying turbulence is investigated by the method of line segments (M. Gauding et al., Physics of Fluids 27.9 (2015…
