← ScienceWhich outcome occurs when backflow through the diffuser in a multistage axial compressor disrupts boundary layer control within the compressor cycle?
A)Blade flutter induces component cracking
B)Surge causes flow reversal✓
C)Stall leads to efficiency losses
D)Vibration induces rapid impeller wear
💡 Explanation
Surge induces flow reversal because the increased pressure stalls the later stages of the compressor; therefore, mass flow rate dramatically decreases, or a reverse flow occurs, rather than vibration or flutter which are related to different imbalance modes.
