Spline Shallow Water Moment Equations
Ullika Scholz, Julian Koellermeier
Reduced models for free-surface flows are required due to the high dimensionality of the underlying incompressible Navier-Stokes equations, which need to fully resolve the flow in…

Spline Moment Models for the one-dimensional Boltzmann-BGK equation
Julian Koellermeier, Ullika Scholz
We introduce Spline Moment Equations (SME) for kinetic equations using a new weighted spline ansatz of the distribution function and investigate the ansatz, the model, and its perf…
