← ScienceWhich effect significantly reduces jet engine thrust, because flow exceeds critical Re?
A)Increased viscous air friction loss✓
B)Improved fuel air mixing flow
C)Enhanced compressor blade efficiency stage
D)Decreased turbulent boundary layer separation
💡 Explanation
High Reynolds number causes flow field transitions leading to increased viscous air friction loss affecting engine thrust. Flow separation occurs near the compressor fan because this elevated value, therefore decreasing thrust, rather than improving combustion which would boost power.
