2D Euler equations - Shock-Bubble interaction
Problem description
A planar shock-wave hits a spere of lower density. Cylindrical symmetry is exploited by employing the two-dimensional cartesian Euler equations and incorporating additional terms by a fractional step method. This example demonstrates the usage of source terms and auxilary arrays.Initial / Boundary Conditions
Numerical Simulation
- Two-dimensional Euler-equations for an ideal gas (Air with gamma=1.4)
- Wave propagation scheme with Minmod wave-limiter and transverse wave propagation
- Calculation with CFL-No. 0.8 to time t=0.2
- AMR-computation with a coarse grid of 300x100 cells
- Calculation of 341 time steps
- 1 levels with refinement factor 2 is used.
- Finest level corresponds to 600x200 grid (120 K cells)
- Calculation of 364 time steps
- 2 levels with refinement factor 2 and 4 are used.
- Finest level corresponds to 2400x800 grid (1.9 M cells)
Results: 2 Levels / 3 Levels
