Adhesion of Cylindrical Particles to Rough Surfaces

Calculation of Adhesive Force for Cylindrical Particles. In addition to spherical particles, particles with other geometric forms may be encountered. In [160] the authors investigated in detail the adhesion of cylindrical particles to smooth and rough surfaces. 

The influence of roughness on the adhesive interaction of cylindrical particles is evaluated in accordance with Eq. (V. 11), which we will represent in the following form  

According to Eq. (V.13), the force of adhesion is a function of the number of contacts i between particle and surface and the number of molecules participating in adhesive interaction. 

Let us now consider in more detail the influence of these factors on the adhesion of cylindrical particles to a rough surface. 

In the case of adhesion of a smooth cylinderical particle to a smooth surface,, in accordance with Fig. V.8, will be given by
