Which outcome reduces jet engine efficiency when above critical Mach number?

💡 Explanation

Shock waves lead to adverse pressure gradients inducing boundary layer separation via Adverse Pressure Gradient because momentum decreases near the surface. Therefore separation decreases efficiency, rather than smooth flow or better combustion resulting from attached uniform boundary.
