Abstract

The hydromangetic stability of bounded fluid jet under the influence of the electromagnetic (with toroidal varying field) force has been developed. A general dispersion relation valid for all modes of perturbation is derived. The geometric factor q which is the radii ratio of the tenuous-fluid regions plays an important role for stabilizing the model. The axial and transvers magnetic fields interior and exterior the fluid jet are stabilizing. The magnetic fields decrease the streaming destabilizing domains and at the same time give a sort or rigidity to the fluid molecules. For any value of the applying magnetic field strength, the instability character of the streaming model could be suppressed and dispersed. These results are confirmed numerically upon using computer programs.
