Stochastic Galerkin reduced basis methods for parametrized linear elliptic partial differential equations
Sebastian Ullmann, Christopher Müller, Jens Lang
We consider the estimation of parameter-dependent statistics of functional outputs of elliptic boundary value problems (BVPs) with parametrized random and deterministic inputs. For…

Entropy-Preserving Coupling of Hierarchical Gas Models
Pascal Mindt, Jens Lang, Pia Domschke
This paper is concerned with coupling conditions at junctions for transport models which differ in their fidelity to describe transient flow in gas pipelines. It also includes the…

POD model order reduction with space-adapted snapshots for incompressible flows
Carmen Gräßle, Michael Hinze, Jens Lang +1
We consider model order reduction based on proper orthogonal decomposition (POD) for unsteady incompressible Navier-Stokes problems, assuming that the snapshots are given by spatia…
