Abstract Dust accumulation and wind effects can form structure-like obstacles on exposed surfaces, making it challenging to remove dust using rolling water droplets, as the droplets encounter obstacles of varying sizes during their motion. Controlling droplet motion over dusty surfaces becomes vital for efficient self-cleaning process.

Abstract A novel approach for mitigating environmental dust from hydrophobic surfaces using a water droplet is presented. A sessile droplet is sandwiched between two parallel plates, one of which is moveable and hydrophilic while the other is stationary and hydrophobic. Investigations are conducted into how plate spacing affects the dust mitigation rate and the droplet's level motion. The high-speed camera analyzes the droplet motion for various plate spacing, dusty regions, and droplet sizes.
