Blown film cooling numerical and experimental investigations

Abstract

The blown film production process involves several processes as extrusion and film cooling. The demand to achieve high productivity with proper film quality has devoted the researchers to investigating in detail, the bubble kinematics, and the thin film cooling process, utilizing the powerful Computational Fluid Dynamics tools, which allows them to deeply study the flow field, and the related heat transfer from the hot thin film to the surrounding mediums, several runs can be done, resulting in huge scientific data, at a minimum cost. In addition to the experimental measurements. The combination of both, reveals better understanding and accurate results.
