The three-dimensional shock-bubble interaction is investigated numerically using high-resolution piecewise parabolic method, in which both the viscous and turbulence effects are considered. The bubble is fixed at the same size and is accelerated by a planar shock wave of different strengths, in which...

Simplify the gyro rotor into a hollow disk, each particle in the disk circular motion around the z axis with High speed. At same time, it around y axis rotation follows the disc. That is, the disk does not rotation, but each particle in the rotor circular motion relative to the disk, at the same time,...
