Experiment and numerical simulation of droplet wetting on weathered red-layer mudstone surface

Key Points

• Droplet wetting on weathered red-layer mudstone surfaces is significantly influenced by surface tension and capillary action.
• Key findings show that droplet dynamics change with varying surface conditions and material properties, affecting overall wetting behavior.
• Experiment and numerical simulation analyze droplet wetting using standard physical models to compare theoretical predictions with real-world behavior.
• Understanding droplet behavior on mudstone surfaces may aid in environmental management and geotechnical engineering.
