Bubble fusion (theory)

Quote from Frogfall

At the temperatures that are usually quoted, it certainly will be plasma - as well as forcing some molecular disassociation. The shock will probably free-up some electrons, just on its own.

Note that on the first video, above, the bubble contacts the surface of the liquid - and the "jet" always starts at the surface. For a bubble deep inside the liquid, the collapse mechanism could be quite different (and possibly spherical rather than toroidal).

Okay, then consider the propagation of a shock wave on the surface of a sphere. Let the wave front start at the equator and move to the north pole and then bounce back to the equator and move to the south pole. At the same time, on the surface of the torus, due to the absence of poles, the movement of the shock wave front along the meridians has no features.

But is implied that the shockwave create the transient condition for a high temperature plasma that would cause fusion. But it is not that simple. There's charge separation and coherence. In that sense the shockwave is important as key to induce the coherent state. But how you model that?

Why don't you admit the possibility that the shock wave itself is the cause of nuclear fusion?

I will note at the same time that thermonuclear fusion caused by the heating of the bubble gas by a shock wave during its compression is considered there, but nuclear fusion from a surface shock wave is not considered.

The above-mentioned article shows that the shock wave of bubble compression is formed at the end of its evolution, at the stage of a sharp increase in the acceleration of bubble compression (formula 4.1). At the same time, the acceleration of the bubble compression rate triggers the mechanism of the surface shock wave, which in turn triggers the mechanism of cold fusion.

Quote from Alan Smith

The inner median line of a torus is of course shorter than the outer median line. This suggests that a wavefront originating at the inner median is stretched and thus less energetic by the time it reaches the outer meridian.

It all depends on the geometry of the bubble. It can even be a torus stretched on a sphere without poles. The main thing here is the mechanism for starting cold fusion by means of a surface shock wave.
