Titel
3D Multiphysics finite element model of a highly nonlinear glass forming process
Abstract
This paper addresses the modelling of a complex glass forming process as an example of a complex, nonlinear distributed parameter system. The system is modelled by a fluid dynamics approach, which means that the forming is regarded as a fluid with free surfaces. Here, the coupling of the forming process with the heat flow is considered. The influence of crucial model parameters (e.g., dynamic viscosity) to the shape of the glass tube and the dynamic behaviour is investigated by means of simulation results. In detail, with the 3D model of the glass forming process the impact of asymmetries of furnace properties to the produced glass tubes have been investigated.
