Question

Advantages of shock waves according to recent studies

Answer 1

In physics, a shock wave (also spelled shockwave), or shock, is a type of propagating disturbance. When a wave moves faster than the local speed of sound in a fluid, it is a shock wave. Like an ordinary wave, a shock wave carries energy and can propagate through a medium; however, it is characterized by an abrupt, nearly discontinuous change in pressure, temperature and density of the medium.[1][2][3][4][5][6]

For context of comparison, in supersonic flows, additional increased expansion may be achieved through an expansion fan, also known as a Prandtl-Meyer expansion fan. The accompanying expansion wave may approach and eventually collide and recombine with the shock wave, creating a process of destructive interference. The sonic boom associated with the passage
