Isotopization of turbulence

The xs4 run is the simulation of a shockwave created by two slabs of turbulent gas colliding. Initially, four replicas of a 512^3 size, blended-down turbulent brick are placed in a row. This makes the simulation’s resolution 512 by 512 by 2048. As the simulation starts, the left two bricks and right two bricks are thrown into each other at a velocity of mach 4. The shockwave created by this collision travels outward at a velocity of around mach . The special boundaries on the right and left ends constantly send in new turbulence bricks to collide with the shockwave. This run demonstrates the rapid isotopization of turbulence after it experiences a shock. This simulation was done on our own Unisys ES7000, using 14 processors, and took approximately 1.5 months to complete. For more information:
