| Abstract: | The three-dimensional (3D) shock wave reflections over two perpendicularly intersecting wedges are numerically studied in
this paper, using the finite volume method which is based on the MUSCL-Hancock interpolation technique and self-adaptive unstructured
mesh. Two kinds of 3D Mach stem structures are demonstrated by the numerical simulations for different shock Mach numbers
and wedge angles. A four-shock or three-shock wave configuration appears in the vicinity of the corner of the wedges. |
