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…
Random field reconstruction of inhomogeneous turbulence. Part I: Modeling and analysis
Markus Antoni, Quinten Kürpick, Felix Lindner +2
We develop and analyze a random field model for the reconstruction of turbulent velocity fluctuations from inhomogeneous characteristic flow quantities provided by RANS simulations…
Commutator-based operator splitting for linear port-Hamiltonian systems
Marius Mönch, Nicole Marheineke
In this paper, we develop high-order splitting methods for linear port-Hamiltonian systems, focusing on preserving their intrinsic structure, particularly the dissipation inequalit…
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…
Splitting Techniques for DAEs with port-Hamiltonian Applications
Andreas Bartel, Malak Diab, Andreas Frommer +2
In the simulation of differential-algebraic equations (DAEs), it is essential to employ numerical schemes that take into account the inherent structure and maintain explicit or hid…
