Overview

Numerical investigation of water entry behaviors in twin wedges reveals significant curvature and spacing effects.

Key Points

  • This study investigates the water entry behavior of variable-curvature twin wedges, aiming to understand the influence of geometry on hydrodynamics.
  • Numerical analysis using multi-phase flow framework and advanced methods for moving boundaries.
  • Systematic parametric study involving five curvature configurations and different spacing and velocity conditions.
  • Utilization of a Cartesian grid for accurate modeling of water impact dynamics.
  • Higher curvature wedges significantly increase peak slamming pressure due to fluid accumulation (exact values not provided).
  • Earlier flow separation occurs in sharper wedges, resulting in lower pressure peaks and load fluctuations.
  • Smaller inter-body spacing leads to greater pressure amplification and flow interaction between wedges.
