This research proposes a comprehensive framework integrating thermodynamic theory, stochastic contact line model, and multiscale computational methodology to address wetting on stochastically rough and fractal surfaces.
Key findings
Proposes a generalized thermodynamic theory for wetting on self-affine fractal surfaces.
Develops a stochastic model for contact line pinning and hysteresis on random rough surfaces.
Investigates metastable wetting states and transition dynamics on hierarchical fractal structures.
Anticipates predictive models for contact angle hysteresis and design principles for superhydrophobic surfaces.
Limitations & open questions
The relationship between fractal dimension and contact angle hysteresis remains a gap.
Stochastic contact line dynamics on random rough surfaces are not fully described.
Metastable state transitions on hierarchical fractal surfaces are poorly understood.
