Level-Set and VOF Hybrid Method in OpenFOAM

Overview

This repository contains the implementation of a hybrid Level-Set and Volume of Fluid (VOF) method for interface tracking in OpenFOAM. The hybrid approach combines the high interface precision of the Level-Set method with the mass conservation benefits of the VOF method, enabling robust and accurate multiphase flow simulations.

The solver is designed for applications such as:

• Free-surface flows
• Droplet dynamics
• Multiphase interactions
• Interface capturing in complex geometries

Features

• Hybrid Level-Set and VOF Approach: Improved interface tracking by leveraging both methods.
• Mass Conservation: Retains the advantages of VOF for global mass conservation.
• Sharp Interface Representation: Enhanced by the Level-Set method's ability to track fine interface details.
• Robust Solver: Built on the OpenFOAM framework for extensibility and flexibility.
• Customization Options: Adjustable parameters for interface smoothing, reinitialization, and flux correction.

Installation

Clone the Repository:

git clone https://github.com/cloner0110/LevelSet-VOF.git
cd LevelSet-VOF/src && wmake

Prerequisites

• OpenFOAM (v2312)

Methodology

This implementation integrates:

1. Level-Set Method: Solves for a signed distance function to track interfaces.
2. VOF Method: Utilizes a volume fraction field for mass conservation.
3. Hybrid Correction:
   • Reinitialization of the Level-Set field.
   • Flux corrections to ensure interface consistency.
