Viscoelastic model hierarchy for fiber melt spinning of semi-crystalline polymers
Manuel Ettmüller, Walter Arne, Nicole Marheineke +1
In the fiber melt spinning of semi-crystalline polymers, the degree of crystallization can be non-homogeneous over the cross-section of the fiber, affecting the properties of the e…
Simulation-based High-Speed Elongational Rheometer for Carreau-type Materials
Lukas Kannengiesser, Walter Arne, Alexander Bier +3
For the simulation-based design of fiber melt spinning processes, the accurate modeling of the processed polymer with regard to its material behavior is crucial. In this work, we d…
On flow-enhanced crystallization in fiber spinning: Asymptotically justified boundary conditions for numerics of a stiff viscoelastic two-phase model
Manuel Ettmüller, Walter Arne, Nicole Marheineke +1
For flow-enhanced crystallization in fiber spinning, the viscoelastic two-phase fiber models by Doufas et al. (J. Non-Newton. Fluid Mech., 2000) and Shrikhande et al. (J. Appl. Pol…
Modeling and Simulation of Curved Fibers in Dry Spinning Scenarios
Manuel Wieland, Walter Arne, Nicole Marheineke +1
Dry spinning is characterized by the simultaneous production of multiple thin polymeric fibers in airflows and the evaporation of the solvent contained in these fibers. This involv…
Melt-Blowing of Viscoelastic Jets in Turbulent Airflows: Stochastic Modeling and Simulation
Manuel Wieland, Walter Arne, Nicole Marheineke +1
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 t…
An Efficient Numerical Framework for Fiber Spinning Scenarios with Evaporation Effects in Airflows
Manuel Wieland, Walter Arne, Robert Feßler +2
In many spinning processes, as for example in dry spinning, solvent evaporates out of the spun jets and leads to thinning and solidification of the produced fibers. Such production…
Whipping of electrified visco-capillary jets in airflows
Walter Arne, Nicole Marheineke, Miguel Perez-Saborid +3
An electrified visco-capillary jet shows different dynamic behavior, such as cone forming, breakage into droplets, whipping and coiling, depending on the considered parameter regim…
Finite volume approach for the instationary Cosserat rod model describing the spinning of viscous jets
Walter Arne, Nicole Marheineke, Andreas Meister +1
The spinning of slender viscous jets can be described asymptotically by one-dimensional models that consist of systems of partial and ordinary differential equations. Whereas the w…
