Question

explain the phenomenon of producing of shock waves

Answer 1

from reddys shock tube the shock wave's are produced

Answer 2

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, temprature and density of the medium
For context of comparison, in supersonic flows, additional increased expansion may be achieved through an expansion fam, also known as a . 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 of a supersonic aircraft is a type of sound wave produced by constructive interference.

Unlike solitons (another kind of nonlinear wave), the energy and speed of a shock wave alone dissipates relatively quickly with distance. When a shock wave passes through matter, energy is preserved but entropyincreases. This change in the matter's properties manifests itself as a decrease in the energy which can be extracted as work, and as a drag force on supersenic objects; shock waves are strongly irreversible processes
