Abstract
AbstractRubber compounds have an increased tendency to flow anomalies depending on the compound ingredients and the processing parameters. Due to wall slip effects, rheological material measurements and the material parameters derived from them are affected by errors, since the fundamental analytical and numerical calculation approaches assume wall adhesion. In the literature, various approaches for the description of wall slip effects exist, which partially lead to negative slip velocities as well as slip volume flows that exceed the total volume flow in the capillary. The purpose of this article is the improvement of an analytical model for the determination of slip velocities for both laboratory and near‐process rheological investigations. A comparison shows the limitations of the established wall slip correction methods and the possibilities of the improved correction method.
