Numerical simulation of flow of highly viscoelastic flow in three-dimensional varying thick slit channel. (English) Zbl 0844.76006
Summary: The distributive law of flow rate is studied for highly viscoelastic flow in three-dimensional slit channel with varying thickness by using finite block element method. As an example, the influence of restrictive block on flow rate is obtained in channel of the extrusion die, and the results of numerical simulation agree with an approximate analytical solution.
