💧 Surface Wetting: Contact Angle Simulator (2D)

2D cross-section simulation of a droplet on a solid surface: adjust solid-vapor, solid-liquid and liquid-vapor surface tensions and watch Young's equation set the real contact angle, classified hydrophilic, hydrophobic or superhydrophobic.

⚙ Under the hood

Adjust the solid-vapor, solid-liquid, and liquid-vapor surface tensions and watch Young's equation set the droplet's contact angle in real time. Compare glass, wax, Teflon, and lotus-leaf presets across hydrophilic, hydrophobic, and superhydrophobic regimes.
