Master Thesis Numerical Simulation of Polymer Flow
2 semanas atrás
An HV cable comprises of different components, i.e. conductor, insulation, sheath, armour wires, etc. The quality of the insulation is largely determined during the extrusion process, where different separate layers of molten polymer are applied in a single operation onto the conductor. Therefore, a thorough understanding of the extrusion process, specifically the behaviour of polymer flow, is essential for improving production efficiency, insulation quality and minimizing material wastage, leading to a more cost-effective and environmentally friendly manufacturing process.
**Thesis description**
The objective of this thesis is to develop an advanced CFD simulation model to enhance the understanding of the extrusion process. The main activities are outlined as follows:
- Data Evaluation: Analyse relevant experimental data from scientific literature and NKT to uncover the underlying physics and mechanisms of the extrusion process.
- Model Development: Create a numerical model to simulate polymer flow within the cross-head of the extrusion line.
- Model Comparison: Validate the simulation model by comparing its results with available experimental data.
- Report Writing: Compile and document the findings, methodologies, and results in a final report.
**Qualifications and requirements**
The required qualifications are:
- Master student in Mechanical Engineering / Computational Mechanics, Material Science or any related field.
- Good knowledge of fluid mechanics, heat
