Abstract : Most known technical problems of fluid mechanics involve a relative velocity between fluid and solid surfaces. The conservation laws of fluid mechanics, however, involve only the properties of the fluid (such as density, viscosity, heat conductivity, and specific heats). The solid surface influences the fluid motion mainly by its displacement effect (its body shape) which is described by potential flow theory. At the beginning of this century Prandtl introduced the boundary layer concept in order to include adhesion at the solid surface as an important additional boundary condition. With the introduction of this parameter of fluid-solid surface interaction within the molecular or atomic contact layer, the theoretical prediction of surface friction drag became possible. (Author)
