Modelling Polymers as Compressible Elastic Spheres in Couette Flow

Blog Article

A model of polymer chains as compressible elastic spheres in flow is presented.The spherical polymer blobs are assumed to compress in simple Couette flow in accord ill tempered gnome with recent rheo-optic measurements on semi-dilute solutions.The experimentally determined decrease in radius with increasing shear iphone 12 price georgia rate is predicted by the model.Furthermore, the model predicts power law exponents for the viscosity-shear rate within the range of measured values for polymer chains.
