Abstract
In this chapter, the methods for dust particle removal from hydrophobic surfaces are presented in relation to the self-cleaning applications. The influence of centrifugal forces on the dust particles located on the rotating disk with hydrophilic and hydrophobic surface characteristics is introduced and the dust particle residuals on the disk are analyzed to explore dust particle adhesion on rotating surfaces. Water-droplet cleaning is also discussed for hydrophobic surfaces. The water-droplet rolling and sliding mechanisms are discussed and their effects on the environmental dust removal from the surfaces are presented. The mechanisms of self-cleaning is discussed and the practical applications for the hydrophobic surfaces are incorporated. The model studies for dust removal by the water droplet on hydrophobic surfaces are introduced and the effects of dust particle density on the dust removal mechanisms are discussed. The case studies are introduced towards the understanding of the environmental dust particle removal from surfaces.
