Modeling dynamic interaction between an emerging water droplet and the sidewall of a trapezoidal channel

- Geometric analysis performed to predict the droplet behavior near channel corner.
- Droplet dynamics depends on corner angle, contact angle and droplet inlet location.
- Model predicts droplet jumping behavior as a function of these variables accurately.
- Model was verified with experiments using two base and four sidewall materials.
- Surface energy analysis also was performed to understand droplet jumping behavior.
