文摘
- •
Runge–Kutta discontinuous Galerkin method for solving two-medium flow is presented.
- •
The initial conditions to Riemann problem can be directly obtained.
- •
Less ghost fluid states and geometrical information across the interface are solved.
- •
Relative mass error is smaller than it is by the same order finite difference method.
