Simplified flow models for Bulkley-Herschel fluids in ceramic paste extrusion are investigated. Exact solutions to models with and without convection terms are derived and discussed. In particular, it is demonstrated that for a certain range of model parameters there exist solidification zones. The effects of the model parameters on solidification-zone formation are rigorously analyzed. Furthermore, the analogy to the widely investigated formation of dead zones in chemical reactor engineering is shown.
