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 with Bike Parts - Miscellaneous - Drivetrain Parts recent rheo-optic measurements on semi-dilute solutions.The experimentally determined decrease in radius with increasing shear rate Towels 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.
