    543== Mixing Problem ==
    644To 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.
