Generation of rotation and shear flow in an imploding liner

We have shown that there exist several techniques that can set the liner into rotation and/or excite an embedded shear flow (dω/dr#0) at any desired depth of the liner material. A common element of all these techniques is the use of properly chosen East-West asymmetric structures, situated either on the liner surface or embedded in the shell. Both rotation and shear flow get enhanced in the course of the liner implosion because of the angular momentum conservation. Initial azimuthally asymmetric structures get very quickly smeared out by the shear flow they have produced (or get blown-off from the surface); this decreases their unfavorable effect as seeds of possible instabilities.
