Finite Element Modelling of free-surface viscoelastic flow: theory and sample case studies

In this thesis the development of a general finite element model for free surface viscoelastic flow is presented. The model uses the weighted residual finite element technique in conjunction with the VOF (volume of fluid) method in Arbitrary Lagrangian–Eulerian (ALE) and Eulerian frameworks for tracking free surface boundaries. Application of the developed model to two different case studies and obtained results are discussed and the capabilities of the model are demonstrated. The first case study is based on the simulation of an injection moulding process. The second case study is based on the modelling of a de-vulcanisation process used for recycling of rubber products.
