This study simulates underwater explosions impacting aluminum cylinders. It provides data on structural response and bubble dynamics, enabling further research into fluid-structure interactions.
Area of Science:
- Fluid dynamics
- Structural mechanics
- Computational physics
Background:
- Underwater explosions pose significant risks to marine structures.
- Understanding the complex interactions between explosions and structures is crucial for safety and design.
- Previous studies often simplified the physics involved in these events.
Purpose of the Study:
- To present simulation data of a near-field underwater explosion interacting with a thin-walled aluminum cylinder.
- To provide a detailed analysis of the fluid-structure interaction dynamics.
- To offer a reproducible simulation framework for researchers.
Main Methods:
- Coupled simulation using AERO-F (fluid dynamics) and AERO-S (structural dynamics) solvers.
- Embedded boundary method and FInite Volume method with Exact two-material Riemann problems (FIVER) for solver coupling.
- Finite element analysis for cylinder deformation and yielding; finite volume for bubble and fluid dynamics.
Main Results:
- Detailed simulation data including structural stress, deformation, fluid velocity, pressure, and bubble dynamics.
- Analysis of cylinder yielding and collapse under explosive loading.
- Validation of the coupled solver approach for complex fluid-structure interaction.
Conclusions:
- The provided simulation data offers a valuable resource for studying underwater explosions.
- The established workflow allows for replication and serves as a foundation for related research.
- This work advances the understanding of cavitation bubbles, underwater explosions, and fluid-structure interaction.
