NUMERICAL MODELING OF WIRES AND FIBERS EXTRUSION
Maria NEAGU, Mircea NEDELCU
Abstract: This paper is an analysis of an extruded wire/fiber cooled by a fluid that flows in the same direction as the workpiece. The governing equations are written in dimensionless form and they are solved using the finite differences method. The obtained temperature and velocity fields are analyzed for different parameters: Peclet number and wire/fiber velocity. This analysis offers a better understanding of the extrusion process and a direct technological application by presenting the variation of the cooling tunnel optimum length as a function of the most important parameter: the Peclet number.
Key words: extrusion, wires, fibers, cooling, forced convection, design, industrial system.
