Excited to share our latest simulation project using OpenFOAM's compressibleInterDyFoam! 🚀

I've recently completed a 2D sloshing tank simulation, showcasing the power and versatility of compressibleInterDyFoam for multiphase flow analysis. This solver is specifically designed to handle the dynamics of compressible, multiphase flows, making it an excellent choice for simulating complex fluid interactions in various engineering applications.

Simulation Details:
- Phases: Air and Water
- Solver: compressibleInterDyFoam
- Dynamic Meshing: Utilized the solidBodyMotionFunction with SDA (Six Degree of Freedom) capabilities to accurately capture the fluid-structure interactions within the sloshing tank.

Key Features:

1. compressibleInterDyFoam:
- Handles compressible, multiphase flow with surface capturing using the Volume of Fluid (VOF) method.
- Solves the Navier-Stokes equations for each phase, ensuring precise modeling of fluid dynamics.
- Incorporates phase-fraction transport equations for accurate tracking of phase interfaces.

2. Dynamic Meshing with SDA:
- Implemented solidBodyMotionFunction to simulate the motion of the tank.
- The Six Degree of Freedom (SDA) model allows for realistic movement of the tank, accounting for translational and rotational motions.
- Ensures that the mesh adapts dynamically to the motion, maintaining accuracy and stability throughout the simulation.

SDA is a motion specific to modeling in marine applications. This was intended to simulate the motion of a vessel in a seaway. The intended application was tank sloshing of a large liquid storage tank in the vessel. In this scenario, the tank would be modeled as the CFD domain, and the SDA motion would be applied to simulate the motions of the ship and drive the tank sloshing.

Applications:
This simulation is particularly relevant for industries where understanding fluid behavior under dynamic conditions is crucial, such as:
- Marine and Offshore Engineering
- Automotive and Aerospace
- Chemical and Process Engineering

Technical Insights:
- The compressible nature of the solver allows for capturing pressure waves and compressibility effects within the fluid phases.
- Dynamic meshing with SDA provides a robust framework for modeling fluid-structure interactions, essential for analyzing sloshing dynamics.
- The VOF method effectively tracks the air-water interface, ensuring accurate phase distribution throughout the simulation.

This project highlights the advanced capabilities of OpenFOAM for simulating complex fluid dynamics scenarios. I'm thrilled to continue exploring and leveraging these tools for future research and engineering projects.
