← ScienceWhich risk increases dramatically post isentropic compression in pulse detonation?
A)Premature detonation reaction rate rise✓
B)Inefficient fuel injection cycle timing
C)Incomplete mixing, lowering engine efficiency
D)Wall quenching increases specific mass
💡 Explanation
The premature initiation risk increases because compression heating drives reaction acceleration. Autoignition occurs, because the Arrhenius equation dictates the reaction rate's extreme sensitivity to temperature. Therefore, autoignition risk rises, rather than predictable combustion from a spark event.
