The motion of suspended particles almost in contact

Abstract The forces and torques on two moving solid particles suspended in a fluid and almost in contact with each other (or on a particle almost in contact with a wall) are found in terms of their relative motion by using a type of lubrication theory, the results so obtained being asymptotically valid for small gap widths. It is assumed that the surfaces of the particles involved if brought together, are such that contact would occur at a single point at which surface curvatures are finite.
