Fluid Dynamic and Thermal Modeling of the Injection Molding Process in OpenFOAM~?

摘要

For the description of the filling, packing, and cooling phases of the injection molding process, a simulation framework of a compressible two-phase fluid model with polymer-specific material models is established and validated with experimental results. With this approach, it is possible to describe the fluid dynamic, the rheological, and the thermal behavior of the material during the production process. The main focus of this work is on the description of the standard injection molding process of common thermoplastic materials for industrial application, with special focus on process relevant quantities, e.g., pressure, temperature, as these values are of utmost importance for understanding the underlying phenomena and comparing the results to experimentally measured values.
