Viscosity divergence and gelation

Viscosity divergence and gelation

A new model of gelation is presented in which the viscosity is observed to diverge without the introduction of shear elasticity when a critical concentration of suspended particles is reached. This viscosity divergence results from the hydrodynamic interaction between the suspended particles and can...

Zusammenfassung:A new model of gelation is presented in which the viscosity is observed to diverge without the introduction of shear elasticity when a critical concentration of suspended particles is reached. This viscosity divergence results from the hydrodynamic interaction between the suspended particles and can be explained using the Random Resistance Network model. A comparison of the data and with other models is also presented.
