Which consequence results when a supersonic airflow encounters backward-facing step?

💡 Explanation

Flow separation increases turbulence downstream of the step involving abrupt pressure changes. This is because adverse pressure gradients trigger boundary layer separation promoting strong mixing; therefore, greater turbulence occurs rather than smooth pressure recovery or diminishing viscosity effects.
