Notes:
A numerical method for analysis of isothermal non-Newtonian polymer melt flow in narrow channels of complex shape is described. This method is applied to the flow in a cable-covering crosshead. The volumetric flow field is calculated and the melt thickness distribution proves to be strongly nonuniform. A series of modified cannel geometries are suggested and the volumetric flow rates in these channels are calculated. One of these channels, which gives a substantially more uniform unsulation thickness, is shown as an improved channel design.
