A shock wave is a type of propagating disturbance. When a wave moves faster than the speed of sound in a liquid, gas or plasma (a fluid, in physics terminology) it is a shock wave.
The flow field can be approximated as a lead shock wave, followed by a 'self-similar' subsonic flow field. In simpler terms, a blast wave is an area of pressure expanding supersonically outward from an explosive core. It has a leading shock front of compressed gases.The blast wave is followed by a blast wind of negative pressure, which sucks items back in towards the center.The blast wave is harmful especially when one is very close to the center or at a location of constructive interference.High explosives, which detonate, generate blast waves.he blast wave is followed by a blast wind of negative pressure, which sucks items back in towards the center.
