Abstract
Based on the classic Tadmor model, a number of mathematical models have been developed for calculating the melting profile in single-screw machines. The most comprehensive of these is the five-zone model from Lindt. All these models can only be solved by numerical methods. Parallel to this, attempts have been made to find analytical solutions which describe the melting profile with sufficient accuracy. In this report a comprehensive analytical solution for the whole premelting- and melting process on barrel and screw with respect to the power law will be given.
