| Abstract: | The velocity field , temperature field, pressure field and the expansion ratio have been investigated by numerically simulating the flow of the incompressible viscoelastic melt through a die in the extrusion process. The calculation method presented in this paper can be used to select the extrusion molding conditions and the dimensions of the dies. |
