- W2020518052 abstract "Conventional cooling systems for the blown film extrusion govern the cooling airflow only in one direction. In contrast, a counter flow system uses two individual jet flows. One jet flow provides the air in draw up direction like used in conventional systems. The other one guides the airflow towards the die. It is possible to cool the film over a longer film surface intensively. In addition, the interaction of the jet flow and the ambient air can be reduced which is responsible for an unsteady heat transfer. In this paper, such a cooling system is investigated in detail, numerically as well as experimentally. The experimental work is done using a modular system for a laboratory blown film line. For the simulation, a process model is used which is able to compute a realistic blown film behavior depending on the actual cooling condition. Therefore, a CFD-analysis computes the temperature of the film and flow phenomena of the jets. A contour calculation model is used to predict the bubble shape. It is based on the framework from Pearson and Petrie and a modified Phan-Thien Tanner model for the rheological description of the tube formation zone. Both modules interact in a loop until a final quasi-stationary blown film contour is found. The aim of this investigation is to get a better understanding of the film cooling using a counter flow system for several different process states. In addition, this knowledge base can help to develop novel cooling approaches. Therefore, a process space is analyzed using a LDPE. To verify the simulation with the experimental results the film contour and frost line are measured." @default.
