Viscous flow of liquids

Henry Eyring s research has been original and frequently unorthodox. He woj one of the first chemists to apply quantum mechanics in chemistry. He unleashed a revolution in the treatment of reaction rates by use of detailed thermodynamic reasoning. Having formulated the idea of the activated complex, Eyring proceeded to find a myriad of fruitful applications—to viscous flow of liquids, to diffusion in liquids, to conductance, to adsorption, to catalysis.

The hydrodynamic resistance of dispersion medium in the gap between particles against flowing out is one of the kinetic stability factors. The decrease in thickness of fluid layer between the particles during coagulation is related to viscous flow of liquid out of a narrow gap between the particles. For solid particles the liquid flow velocity is zero at the interface and highest in the center of a gap. The rate with which the gap between two circular plane-parallel plates of radius r (Fig. VII-7) shrinks, dh/dt, is related to the volume of liquid that flows per second across the side surface of cylindrical gap, dV/dt, via the following relationship ... 

The Maxwell model consists of a spring and dashpot coimected in series (Figure 3.10a). When a load is applied, the elastic displacement of the spring occurs immediately and is followed by the viscous flow of liquid in the dashpot which requires time. After the load is removed, the elastic displacement is recovered immediately, but the viscous displacement is not recovered. 

Thus, we suppose, that via the activation process at viscous flow of liquid the change of AS can be expressed via AH as same as at the phase transition by the first kind. Activation process at given P and T is nonequilibrium, however theoretically it can be always found at given P such hypothetic temperature T, at which the activation transition will be equilibrium. Therefore, at this temperature T ...

It is of some interest to note that the beautiful researches of Polseuille on the viscous flow of liquids were inspired by his interest in the problem of the flow of blood through the capillaries. Later work has revealed, however, that blood, primarily because of the red cells in it, is one of the systems which does not obey Poiseuille s law of flov...

Rheology is a branch of physics concerned with the time-dependent deformation of solids and the viscous flow of liquids. Rheological models can be used to illustrate the nonlinear viscoelastic response of rPET polymer concrete. These models are mechanical comparisons that demonstrate the interrelationship between the elastic and viscous response of polymers. Simple and complex models can be proposed to...
