The simulation on the planar entrance convergence flow of polymeric
melts was made by means of finite element method (FEM) and the ANSYS
software in the present paper. The velocity distributing, the
variation of extension rate, shear rate, and the half natural
convergence angle (
) of the fluid were discussed under different
initial velocities 
The results showed that the velocity of axes
flow increased non-linearly with increasing the axial flowing distance
and reached the maximum at the entrance. The shear rate increased
non-linearly with increasing the radius distance from the center axes
of the flow channel, and it reached the maximum at the entrance. The
reduced while the shear rate increased
non-linearly with an increase of 
and the 
value of the three-dimension simulation was
lower than two-dimension simulation under the same 
Moreover, the simulations were close to the
experimental observations and theoretical estimations reported in the
literature.
