A non-Newtonian, non-isothermal flow analysis including acceleration effects has been developed to simulate the polymer flow in two-dimensional, axisymmetric geometries. The governing mass and momentum equations are solved by a mixed finite element method, in which the velocity components and temperature are interpolated by quadratic functions, and the pressure is interpolated by a linear function. Modeling of the changing feed system geometry is implemented by dynamic meshing. The described analysis is applied to the design and control of a flow regulator. The results describe the behavior of non-steady, viscous flows and are useful for machine design. © 2004 American Institute of Physics [ABSTRACT FROM AUTHOR]
