Warm Two Stream Instability Simulation (2)
Here's another two stream instability simulation. This one runs a bit longer and illustrates the effect I'm thinking of a little better. In essence, the two streams set up a kind of quasi stability, with unadmixed zones outside the boundary area, yet with a boundary zone where incomplete mixing events continuously recur. Even more curiously, occasionally, instability events dominate the whole process. I use the "warm" two stream simulation because it's likely that population mixing is a "noisy" process.
