A normal shock is a shock wave in a fluid that propagates through the fluid with the same speed as the fluid itself. This occurs when the fluid is compressed or expanded, causing the density of the fluid to change in the direction of the shock wave.
Normal shocks are always associated with changes in the direction of propagation and are characterized by a shock wave. The pressure, velocity, and temperature of the fluid are all constant across the shock front, which is a line of discontinuity in the flow.
Normal shocks occur when a fluid is accelerated or compressed suddenly. Examples of normal shocks include the expansion of air through a valve, the compression of a gas by a fan, and the formation of a shock wave in a fluid-filled tube when a plug is removed
