Abstract

A finite volume model has been developed to determine the transient temperature distribution and instantaneous glass flow velocities throughout the pressing and blowing periods of hollow glass forming processes. The glass is assumed to be incompressible and Newtonian fluid during forming. The system of conservation equations is discretized using finite volume method on unstructured meshes. The heat transfer and flow fields are assumed to be axisymmetric which reduces the solution domain into two dimensions. Thermo-mechanical coupling is solved using a decoupled algorithm in which thermal and flow analyses are performed in an iterative manner. The lagrangian coordinate updating technique is used to define the boundary of the domain. The method is validated by the solut
