Numerische Software und Simulation

Optimierungs- und Simulationsaufgaben stellen sich in der industriellen Praxis in vielfltiger Form Ob beim schonenden Umgang mit Ressourcen bei der Optimierung physikalischer Eigenschaften in der Konstruktion bei der Auslastung von Produktionsanlagen oder bei der Planung von Transportwegen und Zulieferung – Methoden der mathematischen Optimierung und der diskreten Simulation helfen

Melt

In melt-blowing processes mico- and nanofibers are produced by the extrusion of polymeric jets into a directed turbulent high-speed airflow Up to now the physical mechanism for the drastic jet thinning is not fully understood since in the existing literature the numerically computed/predicted fiber thickness differs several orders of magnitude from those experimentally measured

Effects of Processing Parameters on the Fiber Diameter

Our air drawing model of polymers in the melt blowing process is verified by the experimental results obtained with our university's equipment The predicted fiber diameters tally well with the experimental data The effects of the processing parameters on the fiber diameters are further investigated in this paper We find that a lower
