Clump Behavior

Before moving on to 3-D simulations, I wanted to see how setting the clump in motion affected the clump behavior. I set the clump velocity at 10 km/s, and reduced the wind by the same amount to keep the relative velocity the same. I tested both the low density contrast (X = 500) and high density contrast (X = 2000) set ups.

There was also a small error in my previous simulations. I forgot to change the ambient temperature to 5000 K as I had stated. The temperature was actually at 1000 K, which means that the shock was not Mach 10, it was more like Mach 22. This doesn't change what we found out about the different solvers and what not. The new set of runs below are with the correct ambient temperature of 5000 K =⇒ M = 10 shock.

These were all done with 2nd order interpolation and the exact Riemann solver, which still seems like the way to go.


Other Stuff

  • The 3-D version of the high contrast, moving clump simulation above is currently running. If that looks good, I can think about using a 2nd clump again, and Z cooling as well.
  • Need to redo the 2.5-D pulsed jets emission maps at higher resolution for the film thingy on Friday
  • Working on 2.5-D pulsed jets paper revisions
