Magnetic stabilization of shock-bubble interactions: Non-monotonic suppression mechanisms in compressible magnetohydrodynamic flows

The study investigates the dynamics of jet suppression and stabilization in shock-bubble interactions under the influence of magnetic fields in magnetohydrodynamic (MHD) systems. By analyzing key metrics such as jet width, magnetic energy, and kinetic energy differences in both transverse (By) and longitudinal (Bx) magnetic fields across various field strengths, we uncover the complex interplay of magnetic forces, including Lorentz forces, magnetic tension, and pressure gradients. The results reveal that transverse magnetic fields exert stronger suppression effects on jet characteristics than longitudinal fields, particularly at intermediate field strengths, where stabilization is most pronounced. Interestingly, the suppression exhibits non-monotonic behavior; weak fields (BI1) show minimal impact, while very high fields introduce saturation effects and dynamic instabilities, reducing the efficiency of stabilization. Furthermore, the onset of suppression is identified, as evidenced by kinetic energy profiles. This behavior correlates with the spatial distribution of magnetic flux components (Bx, By) and energy density (Eb), which highlight the anisotropic and localized nature of suppression mechanisms. The findings provide valuable insights into the optimization of magnetic stabilization for MHD flows, with implications for instability control, flow management, and energy redistribution in industrial and astrophysical applications.
