Abstract : To investigate the process of grinding down of large eddies into smaller ones at high Reynolds Numbers, a finite difference method is used to obtain the periodic solutions of the NavierStokes Equations numerically when the initial motion is assumed to be v sub 1 = cos x sin y sin z; v sub 2 =  sin x cos y sin z; v sub 3 = 0. Mean square kinetic energy and mean square vorticity are calculated and it is found that the numerical method provides estimates of these quantities up to t = 1.90 at R = 200 and up to t = 1.70 at R = 1000.
