Modelling Polymers as Compressible Elastic Spheres in Couette Flow

A model of polymer chains as compressible elastic singtronic speaker spheres in flow is presented.The spherical polymer blobs are assumed to compress in simple Couette flow in accord with recent rheo-optic measurements on semi-dilute solutions.The experimentally determined decrease in radius with increasing shear san antonio spurs robe rate is pred
