Which mechanism reduces nozzle performance during liquid rocket engine ignition?

💡 Explanation

Vaporization shockwave formation occurs because rapid heating and phase change of fuel create local pressure spikes, leading to shockwaves that disrupt flow rather than smooth combustion. Therefore, nozzle performance degrades because of this process, rather than catalytic effects or creep.
