Random field reconstruction of inhomogeneous turbulence. Part II: Numerical approximation and simulation
Markus Antoni, Quinten Kürpick, Felix Lindner +2
A novel random field model or the reconstruction of turbulent velocity fluctuations from inhomogeneous characteristic flow quantities in terms of stochastic Fourier-type integrals…
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…
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…
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…
