Stefan-Reynolds equation

The Hydrodynamic Factor. In order to determine the reasons for the dependence of adhesion on contact time, let us consider the hydrodynamic phenomena taking place as bodies approach or recede from each other. For this purpose it is customary to use adhesion-simulating techniques (see Section 13), particularly techniques involving plane-parallel disks. The hydrodynamic factor, which is governed by movement of the liquid in the gap between the contiguous bodies and which determines the variation of adhesion with contact time in the interaction of plane-parallel disks, can be taken into account by means of the Stefan-Reynolds equation [96],...
