Some effects - guiding, splitting and
branching
of the objects
As it was noted in the previous
section, the HVEWD plasmoids have tendency to be attracted by nearly
placed conductors being under potential, that can be explained by influence
of the electric field. This effect, called guiding, is well-known
for ball lightnings, observed in the natural conditions. The guiding appears
also in distortion of the object and even can results in the splitting
of the latter, especially if air dynamic flows influence has opposite
direction.
Another interesting and more rare phenomenon consists
in abrupt change of the propagation direction of the plasma flow,
ejected from the central electrod, with forming an angle. In some cases
a secondary branch forms in this region, that is why this phenomenon was
called branching.
On the right image the plasma channel has two area of
bending. In the first one (near to center of the image) the formation of
a secondary branch, directed to the right, is apparently seen, while in
the second region (below "hat") only bending of plasma channel occurs.
