A short note on the stability of a class of parallel Runge-Kutta methods
Friedemann Kemm
With this short note, we close a gap in the linear stability theory of block predictor-corrector Runge-Kutta schemes originally proposed for the parallel solution of ODEs.
New options for explicit all Mach number schemes by suitable choice of time integration methods
Friedemann Kemm
Many low-Mach or all-Mach number codes are based on space discretizations which in combination with the first order explicit Euler method as time integration would lead to an unsta…
Numerical investigation of Mach number consistent Roe solvers for the Euler equations of gas dynamics
Friedemann Kemm
While traditional approaches to prevent the carbuncle phenomenon in gas dynamics simulations increase the viscosity on entropy and shear waves near shocks, it was quite recently su…
A simple diffuse interface approach for compressible flows around moving solids of arbitrary shape based on a reduced Baer-Nunziato model
Friedemann Kemm, Elena Gaburro, Ferdinand Thein +1
In this paper we propose a new diffuse interface model for the numerical simulation of inviscid compressible flows around fixed and moving solid bodies of arbitrary shape. The soli…
A Numerical Study of Newton Interpolation with Extremely High Degrees
Michael Breuß, Friedemann Kemm, Oliver Vogel
In current textbooks the use of Chebyshev nodes with Newton interpolation is advocated as the most efficient numerical interpolation method in terms of approximation accuracy and c…
