    22= Colliding Flows =
    33This problem involves colliding two ellipsoidal cylinders essentially head on where the separation between the left and right flows is an arbitrary interface defined by a normal and a series of sine waves.

     5== Mixing Problem ==
     6To understand the mixing properties of colliding flows we focused on non-shearing interactions.  The gas density is fixed at 3 particles/cc (free fall time of 20.5 Myr) and the temperature at the equilibrium value of (730 K) giving a sound speed of 3.17 km/s and a Jeans length of 116 pc.

     15There are 6 runs total, in which we vary the diameter of the flows between 20, 40, and 60 pc as well as the velocity from Mach 1.5 to Mach 3.
