AB  - The extrudate swell phenomenon is analysed by solving, simultaneously,
the Navier‐Stokes equations along with the continuity equation by
means of a finite volume method. In this work, the planar jet flows of
incompressible viscous Newtonian and power‐law fluids for Reynolds
numbers as high as 75 are simulated. The method uses the velocity components
and pressure as the primitive variables and employs an unstructured
triangular grid and triangular or polygonal control volume for each separate
variable. The numerical results show good agreement with previously reported
experimental and numerical results. Shear thickening results in an increase
in swelling ratio, while the introduction of surface tension results in a
describes in swelling ratio.
