Embodiment 1
[0220] Embodiment 1. Classical normal shock wave reflection calculation example. The lower boundary is the reflective boundary, the left and upper boundaries are the Dirichlet boundary, and the right boundary is the supersonic exit. The calculation area is [0,4]×[0,1]. The numerical results are as follows figure 1 shown.
Embodiment 2
[0221] Embodiment 2. Calculation example of flow around a supersonic cylinder. The calculation area is [-0.5,0]×[-0.5,0.5], the radius of the cylinder is 0.05, the center of the circle is at the origin, and the inflow velocity is Mach 3. The numerical results are as follows figure 2 shown.
Embodiment 3
[0222] Embodiment 3. Calculation example of flow around a supersonic NACA0012 airfoil. The calculation area is [-1.5,1.5]×[-1.5,1.5], the inflow velocity is Mach 2, and the impact angle is 1 degree. Its numerical result is as image 3 shown.
