What does this research mean for the field?

During oblique water entry, spatiotemporal asymmetry in cavity dynamics is driven by a non-uniform pressure distribution, where the upper cavity boundary experiences a weaker adverse pressure gradient than the lower boundary, resulting in significantly greater radial growth and expansion duration. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To determine the quantitative scaling laws and physical mechanisms that drive asymmetric cavity expansion and contraction during oblique water entry.

Implication

Theoretical and numerical modeling demonstrates pronounced cavity asymmetry during oblique water entry, indicating that pressure imbalances govern projectile stability.

Key Points

To determine the quantitative scaling laws and physical mechanisms that drive asymmetric cavity expansion and contraction during oblique water entry.
Coupled theoretical and numerical modeling by integrating projectile velocity decay into the classical constant-velocity cavity boundary model.
Multiphase flow simulations to evaluate pressure gradients, flow-field velocity distributions, and asymmetric cavity boundaries.
The maximum radius of the upper cavity boundary exceeds that of the lower boundary by up to 99%.
The expansion duration of the upper cavity boundary exceeds that of the lower boundary by up to 163%.
Asymmetry is dictated by dynamic pressure imbalances, where a weaker adverse pressure gradient on the upper boundary requires less work to sustain radial growth.
