ONE-DIMENSIONAL EQUILIBRIUM SPECTRA IN ISOTROPIC TURBULENCE. II
Abstract
IT IS SHOWN THAT WHEN A CUT-OFF IS IMPOSED ON Heisenberg's equilibrium spectrum the cut-off wave number cannot be assigned arbitrarily but must have the value k = 3KH /8 ) .2 3 1/4 The energy spectrum is then of the form E(k) = (8 /9KH) k2/3 -5/3 for 0 < k < k and zero otherwise. The velocity and pressure correlations corresponding to this spectrum are then obtained. From these results it is then possible to determine the ratio of the mean-square pressure gradient to the mean-square viscous force. For KH = 0.45, this ratio is found to have a value of about 30.
