Extrusion is a process widely used in the polymer processing industry. It involves pushing material through a die with a specific cross-sectional shape, resulting in products like profiles, thin sheets, films and tubes. However, the shape of the final product (the so-called extrudate) is highly influenced by a phenomenon called swell. Ph.D. candidate Michelle Spanjaards has developed a numerical model that reduces this problem. She will defend her thesis at the department of Mechanical Engineering on Friday 21 of January.
