HYDRODYNAMIC ASPECTS OF MACROMOLECULAR SOLUTIONS.

Abstract

The report is an attempt in very brief form to: review some important concepts involving disperse systems (such as thermal forces, entropy, and strain energy); discuss the dynamics of molecular response to the motion of the solvent; introduce and discuss the idea of critical strain rates, which arises naturally in the theory of molecular response; relate molecular strain to fluid stresses through the use of Mohr's Circle; discuss in a speculative way the role of fluid stiffness in turbulent flows, as for example in providing a mode for the extraction of turbulent energy from an eddy through the generation of elastic shear waves. Finally, it is speculated how the possibility for radiation damping may result in a two or three-fold thickening of the viscous sub-layer. (Author)
