The Hybrid 1D/2D flow model for non-Newtonian fluids in a single cavity die with a slit is presented. The equations of mass and momentum in a cavity are treated one-dimensionally by assuming an appropriate mean flow over the cross section of the flow. The governing equations inside the slot are treated two-dimensionally by the lubrication theory and assuming an appropriate mean flow. The equations of flow for the cavity and the slot are derived and then coupled. We use a finite element method to solve these governing equations. It is concluded that slot's geometry, fluid properties and machining accuracy affect the uniformity of the flow from the slot.
