Which mechanism limits isentropic volumetric efficiency in turbocharger cycles?

A)Internal turbulence energy dissipation
B)Blade fatigue surpassing design threshold
C)Intercooler condensation freezing catalyst
D)Wastegate valve material bond failure

💡 Explanation

Internal turbulence causes energy dissipation, reducing isentropic efficiency because the kinetic energy imparted to the air during compression is not fully converted to pressure; therefore, volumetric efficiency drops, rather than primarily material failure or catalyst issues.
