WebWeißenberg-Rabinowitsch Correction. Due to shear thinning of polymer melts with pseudoplastic flow behaviour a strong flection of the velocity profile close to the wall occurs. This effect is covered by the Weißenberg-Rabinowitch correction. Consequently the shear rates near the wall are higher than these from Newtonian fluids, where the ...
