What flow property(ies) is(are) constant across a shock wave? What do you call that kind of flow?

Solution

when an object moves faster than the speed of sound, and there is an abrupt decrease in the flow area, the flow process is irreversible and the entropy increases. Shock waves are generated. Shock waves are very small regions in the gas where the gas propertieschange by a large amount. Across a shock wave, the static pressure,temperature, and gas density increases almost instantaneously. Because a shock wave does no work, and there is no heat addition, the totalenthalpy and the total temperature are constant.
