Christian Klingenberg

research interests:

• mathematical fluid mechanics

• compressible gas dynamics, magnetohydrodynamics

• kinetic modeling, kinetic modeling of gas mixtures and of plasma, numerics for this

• theory of hyperbolic conservation laws: well-posedness in one and multiple space dimensions, relaxation limits, discontinuous flux conservation laws

• modeling macroscopic fluid flow equations via microscopic interacting particle systems

• numerics for hyperbolic conservation laws: finite volume schemes in one and multiple space dimensions, approximate Riemann solvers, discontinuous Galerkin methods, moving mesh methods

• low Mach limits for the Euler equations and equations of ideal magnetohydrodynamics, also with gravity, both theoretical and numerical

• well-balanced schemes applied to the Euler equations and equations of ideal magnetohydrodynamics, both with gravity

• numerical methods that preserve stationary solutions for for kinetic and fluid equations

• uncertainty quantification, theoretical coercivity estimates, numerical simulations for kinetic and fluid equations

• astrophysical applications: accretion discs, protostellar jets, turbulence modeling, large eddy simulations, star formation, stellar evolution, galaxy evolution
