fuel residence time

基本解釋

Due to extremely short residence time of supersonic airflow, it is difficult to effectively mix and combust for the fuel and air in scramjet combustor.
高超聲速氣流在燃燒室的停留時(shí)間非常短，使得超燃沖壓發(fā)動(dòng)機(jī)燃燒室內(nèi)燃料與氣流的混合及其燃燒變得非常困難。
It is also recognised that bulk density has considerable impact on gas quality, as it influences the fuel residence time in the fire box, fuel velocity and gas flow rate.
它也認(rèn)識(shí)到，體積密度的氣體質(zhì)量相當(dāng)大的影響，因?yàn)樗绊懺诨馂?zāi)中燃料的停留時(shí)間，燃油流速和氣體流量。
