Design of Provably Physical-Constraint-Preserving Methods for General Relativistic Hydrodynamics
Kailiang Wu
The paper develops high-order physical-constraint-preserving (PCP) methods for general relativistic hydrodynamic (GRHD) equations, equipped with a general equation of state. Here t…

Physical-constraints-preserving central discontinuous Galerkin methods for special relativistic hydrodynamics with a general equation of state
Kailiang Wu, Huazhong Tang
The ideal gas equation of state (EOS) with a constant adiabatic index is a poor approximation for most relativistic astrophysical flows, although it is commonly used in relativisti…
Admissible state and physical constraints preserving schemes for relativistic magnetohydrodynamic equations
Kailiang Wu, Huazhong Tang
This paper first studies the admissible state set of relativistic magnetohydrodynamics (RMHD). It paves a way for developing physical-constraints-preserving (PCP) sche…
A stochastic Galerkin method for general system of quasilinear hyperbolic conservation laws with uncertainty
Kailiang Wu, Huazhong Tang, Dongbin Xiu
This paper is concerned with generalized polynomial chaos (gPC) approximation for a general system of quasilinear hyperbolic conservation laws with uncertainty. The one-dimensional…
