TABLE OF CONTENTS To simulate turbulence, set V = -3000, ? t = 1.0(10) -6, J = 40000, Figs. 6.11 6.13 show the flow development at the respective times 0.04, 0.08, 0.12. At t = 0.12, the time step had to be decreased to 5.0(10) -7 to avoid instability. Figure 6.14 shows the turbulent flow at t = 0.15 with J = 60000, to make up for the decrease in time step. Entirely similar results for Figs. 6.11 6.13 followed with J = 30000, 20000, 10000, while results entirely similar to that in Fig. 6.14 followed for J = 80000, 70000, and 50000. In all the figures, the velocity vectors were decreased by vm = 0.003 for graphical clarity. Figure 6.12 compares most favorably with Fig. 2.14 while Fig. 6.14 compares most favorably with Fig. 2.16.
In searching for small vortices, attention was confined to within a circle of radius 1 cm around each particle. There resulted at t = 0.12 355 small vortices which are shown in Fig. 6.15. Moreover, Fig. 6.16 shows the distribution of 349 small vortices at the time t
