Micro-jets generated by defects in inertial confinement fusion (ICF) capsules are widely recognized as a primary cause of implosion performance degradation. However, the inherent three-dimensional (3D) and nonlinear nature of these defects presents significant challenges for detailed investigation of their evolution. This study examines the impact of various low-density defect geometries in ICF capsules using a simplified 3D planar model. Compared to spherical defects of equivalent size and position, cylindrical defects exhibit stronger interactions with the ablation front following shock wave transmission, leading to greater perturbation growth. In contrast, The 3D vortex ring produced by shock interactions with spherical defects propagates significantly faster than the vortex pair formed by cylindrical defects. This accelerated inward material transport by the vortex ring can result in a counterintuitive effect: smaller ablation front perturbations, yet an increased risk of implosion performance degradation. The vorticity and enstrophy transport analyses demonstrate that baroclinic generation and subsequent compressional amplification of vorticity occur in both cylindrical and spherical defects. Notably, the unique vortex stretching associated with spherical geometries is identified as the dominant driver behind the enhanced propagation speed of vortex rings. These findings provide a mechanistic explanation for the additional sources of decompression observed in ICF implosions.
