← ScienceWhich risk increases when injected jet fuel exits engine nozzles?
A)Rapid pressure oscillation amplification downstream✓
B)Accelerated uniform oxidation of hydrocarbons
C)Boundary layer laminar flow adhesion
D)Decreased entropy without thermal transfer
💡 Explanation
Rapid pressure oscillations emerge downstream because momentum transfer due to turbulence triggers amplified vortex shedding. Therefore, pressure oscillations grow, rather than decay, because turbulence adds energy to the system, rather than dissipating it via laminar flow.
