An equivalence of moment closure and nonlinear variational approximation of the Fokker-Planck equation for dilute polymeric flow
Caroline Lasser, Stephan B. Lunowa, Barbara Wohlmuth
We establish the equivalence between a classical moment closure and a nonlinear variational approximation of the Fokker-Planck equation for dilute polymeric flow in the linearized…
Effective permeabilities for flow through anisotropic microscopic geometries
Loïc Balazi, Fabian Holzberger, Stephan B. Lunowa +3
This work develops a computational and theoretical framework for determining effective permeabilities in anisotropic microscopic geometries containing dense, fibre-like obstacles,…
Numerical simulation of dilute polymeric fluids with memory effects in the turbulent flow regime
Jonas Beddrich, Stephan B. Lunowa, Barbara Wohlmuth
We address the numerical challenge of solving the Hookean-type time-fractional Navier--Stokes--Fokker--Planck equation, a history-dependent system of PDEs defined on the Cartesian…
A lattice Boltzmann method for Biot's consolidation model of linear poroelasticity
Stephan B. Lunowa, Barbara Wohlmuth
Biot's consolidation model is a classical model for the evolution of deformable porous media saturated by a fluid and has various interdisciplinary applications. While numerical so…
A Lattice Boltzmann Method for Non-Newtonian Blood Flow in Coiled Intracranial Aneurysms
Medeea Horvat, Stephan B. Lunowa, Dmytro Sytnyk +1
Intracranial aneurysms are the leading cause of hemorrhagic stroke. One of the established treatment approaches is the embolization induced by coil insertion. However, the predicti…
On the Convergence of Learning Algorithms in Bayesian Auction Games
Martin Bichler, Stephan B. Lunowa, Matthias Oberlechner +2
Equilibrium problems in Bayesian auction games can be described as systems of differential equations. Depending on the model assumptions, these equations might be such that we do n…
