Which efficiency loss occurs when a turbine utilizes a Carnot cycle’s heat exchanger at supersonic flow?

💡 Explanation

Irreversible aerodynamic shock heating degrades the efficiency, because energy is dissipated by viscous effects via increased entropy during shock wave formation, thereby lowering available energy by exergy destruction, rather than efficient work extraction.
