Developments on Computer Simulation of Injection Moulding - Modelling With Boundary Element and Finite Element Methods

[摘要] Several mathematical models which are based mainly on the boundary integral equations are developed for computer simulation of injection moulding. The models are then implemented for the viscous flows in the filling stage, and the temperature field during the cooling stage of the process. Starting with the modelling of nonisothermal laminar flow in ducts, the dependence of viscosity on the pressure, temperature and shear rate is taken into account, and the velocity and temperature solutions to fully developed flow are developed. The solutions are used to obtain the approximate axial solutions and possibility of choking is discussed. The solutions are further extended to the cases of a slightly tapered circular pipe, and of cross sections of any shape the latter of which uses a boundary element model.
