Colliding Alumin(i)um Plasmas

The point of these simulations is to study cooling instabilities that may be present in Francisco's experiments of colliding jets. To simplify the problem, the simulations are just 2-D colliding flows with the appropriate Al cooling. The initial parameters are as follows:

T = 10 eV

rho = 10 ug/cc

v = 60 km/s

Z = 6 (ne/ni the electron to ion number density ratio)

The grid is 2 x 2 cm and 64 x 64 cells with 6 levels of AMR. The total runtime is 100 ns.

In the experiments, the "ambient" is a vacuum. To get around this in astrobear, I initialized the flows such that they already fill the domain. So the flows immediately collide at the beginning of the simulation, and they continue to flow in from the top and bottom boundaries. The left and right boundary conditions are periodic.

Below are images and movies of the temperature in eV, and also the density in ug/cc. They are enlarged to look at the region of interest.
