Abstract

In this publication we are dealing with the models of the one-dimensional, isotherm plugflow. Some of these models suppose an isotropic pressure distribution in the polymer plug, while in others the authors are taking into account the non-isotropic pressure distribution which is the real case. Starting from the equations of the continuity and the impulse it's possible to write the balances of the forces and the moments.
