Consider a steady flow through a horizontal divergent channel, as shown in the figure, with the supersonic flow at the inlet. The direction of flow is from left to right.
Pressure at location B is observed to be higher than that at an upstream location A. Which among the following options can be the reason?
1
Since volume flow rate is constant, velocity at B is lower than velocity at A
2
Normal shock
3
Viscous effect
4
Boundary layer separation
