Abstract: The irreversibility of the second law of eddy thermodynamics, developed by Blackadar, depends in part on the fact that the mean flux of eddy energy relative to a surface moving with the mean fluid motion is in the direction ...

Abstract: The variations of the mean-motion kinetic energy and the eddy kinetic energy with scale of averaging are studied in a laboratory experiment of small-scale turbulence. Velocities and velocity products are spatially averaged ...
