A Review of Slip Flow in Continuum Physics,
Abstract
In the study of fluid-solid surface interactions the concept of slip of a fluid at a solid wall serves to describe macroscopic effects of certain molecular phenomena. Macroscopic slip may be divided into the following two types: (1) Real slip, for which molecular interactions cause slip to take place in the bulk fluid, such as in the rarefied gas regime; in flows through minute capillaries and porous media at atmospheric pressures if the dimensions of the pores are comparable to the molecular mean free path of the gas; in certain non-Newtonian fluids; and in mass diffusion theory. (2) Pseudo slip, which corresponds to the use of fictitious slip conditions to obtain useful models for complicated flow problems, such as those involving suspensions and liquid flows over permeable material and grooved plates.
